I absolutely suck at aquascaping

[cvrle1]

I was never artistic person, best I could draw was a stick man. Up until this point in my life it wasnt really too much of an issue, but I think it has finally caught up with me. I absolutely suck at aquascaping. Issue that I have is that I cant visualize what I can do with rocks that I have. I have a bunch of rocks, some small, some bigger boulders, all different shapes, but when I look at them I have absolutely no idea where to start and how to start creating aquascape with them. I kinda have an idea in my head on how I would like scape to look like, but have no idea how to take rocks that I have and mold them into what I want. I am afraid to just start randomly breaking, chiseling and cutting rocks as then I may break something I actually needed to be one piece later on.

Any help or pointers would be much appreciated.
