If you buy your own, PLEASE find something that uses gas shielding, and get small bottle of gas. Its 10000000x easier when your learning, especially on only 120v.
The biggest thing is just to start welding. Get a check of decent scrap (not painted or nasty) and lay beads. Grab different thicnkess stuff and get used to heat and wire speeds. Once you can "feel" how you need to move to get the pool to move, and get a few good beads your confidence level will go way up. I'm not an amazing welder, but I taught myself enough to function, and now I only have to outsource a few things here and there for stuff I can't to (aluminum)
