I have found that it is best for me to start out with just learning the basics of a planted tank. How much substrate to use, how to clean it, how to get it into the tank, how to set out the plants of various kinds, how to add the water, what kinds of rocks work best, how to use wood in the aquascape, how to manage the filtration and lighting, etc. For me, that meant starting with lower light, with fast growing stem plants, with cheap substrate, etc. When I reached the point where I didn't feel a need to look up something everytime I did something, I could then start looking at other plants, other substrates, etc. Eventually, I could begin thinking about making a nice aquascape.
This isn't the only way to start the hobby, and probably not the best way for everyone, but I never stopped enjoying what I was doing while doing this. If I had struggled from the start with higher light, specific plants, a well aquascaped tank, etc. I suspect I would have dropped the hobby.
Perhaps the best thing I ever did was watch experienced planted tank people going through setting up tanks, doing maintenance, etc. So, joining a local planted tank group, and trying to get to watch them do their thing, can be a very big help, much better than just reading about it.
