I agree with Don, Fox and GM here. Don't fret over your first few kits, the learning curve on some of the stuff you see on the forums can be steep I.E. airburshing those perfect panel lines LOL, after 52 years I still can't get it right. Mostly all the techniques you see are trial and error and a lot of the time. You will eventually find your own way of doing something. Like GM said, try different genera's. You may really like planes or cars but find that armor or ships are really your thing. Most of us build everything but tend to stay with a certain genera or two that we know we can do well. I stink at figures, but I like to venture out of my comfort zone on occasion and give them a whirl. Then I run back to momma and go back to building planes and ships.
Also, YouTube is a good source but there are many "tubers" that are just a waste of time. BTW, I'm doing some tutorial vids on my water technique, they won't be a waste of time , poor editing and silly confused sounding host, but not a waste of time.
I like Andy's Hobby Headquarters and PLASMO just to name a couple, there are several others. Andy is quick and dirty, but his stuff looks great when completed (I do get a little tired of the same classical music though) and PLASMO is a young Rembrandt IMO.
As Don said there are several publications from Kalmbach that are excellent as well.
Above all else, this hobby is supposed to be relaxing. When you're finished with a build, if you like it that's all that matters.
