Oh I know exactly where you're coming from. Been there. The best advice that I was ever given was to just have fun with it. If it's not fun then don't worry about it, make it a learning experience.
Why don't you do some practice technique blocks, and don't have a specific project in mind. Keep making different blocks in different colors that you want to try. Focus on the method of making them rather than getting everything "perfect"
Nothing I make is "perfect" but as long as I have fun that's what matters.
