First of all, a great topic with lot of interesting viewpoint.

There are no such thing as failure. Its a learnig process.
It’s a given that you need some equipmen, but in my opinion there are several way to achieve your goal in this hobby.

Some of them i think, is that you are willing to learn. Learn and read, listen to people with experience. (They have probably ”at some time” had the same problem as you)
I also feel that some patient with your scaping is of importance. Some of the great Aquascape we can see on the net did not growth over night.

And remember, learning is a never ending process.
