Treat poeple the way you would want them to treat you.
When you screw-up, fess up, and move on.
Give a full day's work for a full days pay.
Take time to laugh every day.

How do I change a flat tire?
How to change a Flat Tire
Step One: Setting the scene
Scene is safe. Flat tire or not a vehicle needs to be in a safe spot before you can attempt repair. Try to start out in a fairly level place well out of traffic. A car can be moved a short distance on a flat at very low speeds, think football fields not 1/10s of miles. If you are on the side of the road make sure your flashers are on.
Step Two: Safety
Put on emergency brake and straighten front tires - put an automatic in park, low gear or reverse for a standard transmission. - You don't want your car to roll while there's no a tire on it.
Step Three: Inventory
Do you have a jack, spare, lug wrench, something to get hubcaps off with? You can not do much of anything without the right tools. Have them in reach and not in the car or truck, once the tire is off you don't want to be bouncing the car around while it is on the jack. Passengers should know to get out or sit still while you are changing the tire.
Step Four: Using your tire tool
All cars have lug-nuts some you have to take off a hubcap to get to. A screwdriver can usually be used to pry at the edge og a hubcap at short intervals all around until it comes loose. Once you can see the lug-nuts you will put your tire tool on the lug-nut pointing at what would be 10 o'clock on a clock face. This allows you to push down on the end of the lug wrench or even step on it if you aren't strong enough, just be careful to ensure it is on well before you exert maximum force or you could brake the lug or strip the lug-nut. You should be able to turn them 2-3 turns until they become easier to tun then stop you have to jack up the vehicle before you go any further.
Step Five: Using the jack made for your vehicle
I wont go into this cause there's too many jacks that all work differently for different vehicles
- jack up the corner of the car where the flat is. Try to make sure the ground under the jack is solid
so it doesn't sink in the mud as it lifts the corner of the car. A short length of board can be placed under a jack in some cases to help support the jack. Jack the car up just enough to fit the spare on - the higher the less stable and less safe.
Step Six: Take Precaution
Finish loosening the lug nuts and wiggle the flat off of the studs. Being careful not to bump the jack slide the flat under the car as an additional safety if it were to fall off the jack. Do no place your arms legs or torso or head under the car or suspended axle.
Step Seven: Putting spare on studs
Align your spare tire up with the studs and lift it into position -don't jostle or bounce the car while pitting it on. Start one lug-nut, being careful not to cross thread it and tighten it with the lug wrench until it is just past finger tight. Then start one straight across from it and continue in a star pattern pulling the wheel squarely onto the axle. Once all lug-nut are on and just past finger tight start over and tighten them pretty tight and finally one more time around tightening them to the manufacturers recommended torque. Don't overt-tighten or the studs may break.
Step Eight: Now you are ready to pack up and hit the road.
Drag your flat out from under your car and slowly let down the jack. Pack up all your tools and hubcap. Don't forget your flashers are on you can turn them off now and let off your emergency brake.Go carefully down the road to get your tire fixed or a new one. Remember you don't have a spare now and you may have not gotten your lug-nuts tight enough. If your spare is a temporary or donuts sized spare you must not exceed the speed that the spare was rated for and your auto will handle different with the odd ball spare. Good luck!

How do you weld?
I recently learned how to weld and , I am far from an expert but I can tell you how I went about it.
I learned on an arc welder , also called a stick welder.
Welding is the fusing of two pieces of metal together by melting them and an electrode with high voltage electricity.
Welders have two leads (wires coming out of them)-a hot and a ground.
The ground connects securely to one of the pieces you are wanting to join together. you may have to use a grinder or wire brush to make sure it is connected to metal well and not grease or rust or dirt.
Once the ground is connected you should secure a welding rod in the lead. One end of the rod has no flux on it this is the end that is pinched int the jaws of the lead. All rods have numbers on them that specify how many pounds per inch a properly welded connection will hold. i have used rods that start with 60 or 70 there is a chart on most welders saying what setting the welder should be set on to weld with certain rods. There is a second set of numbers also that specifies what kind of flux is on the electrode and what it is good for.
6011 or 6013 is a good rod to learn on 7018 is a little harder to work with but makes an extra strong bond.
Flux is the coating on the electrode The reason flux is on the rods is --as the electrode melts the flux burns intensely creating an oxygen free zone over the molten metal and also preventing the molten electrode from sticking to the weld.
You want to always wear darkened eye cover while welding because the intense light can damage your eyes.
So what happens is when the electrode contacts the the metal that is attached to the ground a circuit is closed causing lots of energy to stream through. Electric energy creates heat when it moves and the tip of the electrode will be the smallest place and thus the most concentrated amount of heat. As the heat cooks the flux it boils and the boiling flux melts the metal, the electrode , and the other piece of metal all into a tiny pool or drop of molten metal.
That tiny bright red pool is where the magic happens because, as the electrode melts, tiny gaps open up between the new end of the electrode and the drop of molten metal. The electricity jumps (or arcs) from the electrode to the pool. This ark is hot as lightening - hotter than the surface of the sun. This arc can be aimed to send the heat deep into the two pieces you are joining melting the surface and the two molten surfaces and the metal from the electrode join as new metal. As the new metal cools imperfection come to its surface. The impurities take the form of a carbon type substance called SLAG. Slag protects the cooling weld and then is chipped off with a tiny pointed hammer or grinder to re-weld, most large welds require several passes to make sure there is enough metal n the joint to hold tight.
