I have a sneaking suspicion that nearly everyone on this forum started out exactly where you are right now. Step by step, like everyone's saying, is the key. Take the time to appreciate each little tiny advance that you make. When (not if) you get confused/frustrated/bogged down, here's what you do:
Take a picture of it.
Leave your shop area.
Pour yourself your favorite beverage.
Get on your computer.
Navigate to this forum.
Post the picture, and your question.
Turn on the teevy, watch a ball game or something.
Come back to your computer a while later.
You'll probably have an answer, maybe more than one.
You'll find the encouragement & advice invaluable.
Remember there are no "dumb questions." Even if a hundred people have been there/done that, you haven't, and guidance is readily available. You may run into a situation that seems so weird that nobody could possibly have screwed this up that badly before... but I'll bet someone here has!
On rare occasions, an answer might sound rancorous, or perhaps even testy. Very nearly 100% of that is simply due to the loss of visual & verbal cues that plagues email & forums. Don't ever take it personally... it's certainly not intended that way!
There's no competition here, to get things done fastest, or best. Take your time; in the long run, you'll be glad you did.
