Like most are saying, it really isn't as hard or as overwhelming as it seems at first.

Sure it's possible to screw it up, but if you're reasonably careful it's extremely unlikely.

You're far more likely to screw up after about 40 rolls of film when you feel like you have it all licked and you don't label your containers well so you pour in the fixer first. (Three guesses how I know that!)

Relax, and keep it in perspective that this isn't a job interview. Everybody here, and I mean literally everybody, is willing to help.

Sacrifice a roll of film to figure out how to load the reel in the light. Try pouring water in and out of your tank so you know how the pouring is "really" going to go. Then measure the chemicals and go.

if your negatives are a little hard print a little soft. If they are a little soft print a little hard.

While it is true that superlative work can require exacting procedures, when you're just starting out this is a lot more forgiving than many activities. Blowing up a race car engine is real expensive.
