Meditate or go for a walk.
Dream smaller and work within your creative means.
It's easy to be overwhelmed by hundreds of ideas, so just choose one idea that expresses a lot instead of many ideas that express little bits here and there.

It's ok to keep your creative work simple,.in fact some of the best work is good because it's simple :) impulse and attention deficit are flaws of mine too, but I learned to work with them not against them by having some patience and self compassion.

Thanks hon, I really appreciate it. I really should try to simplify and strive for the little accomplishments, but a lot of times I have trouble with feeling like the payoff won't be enough. I find that small projects can still get pretty tricky and even daunting at times. I start to think stuff like, "so what if I clear this hurdle? the thought of getting this project done doesn't seem exciting enough to justify the challenge." It's not really the difficulty side of the equation (though I struggle with that too), it's more the reward side, I kinda just have problems with... being happy with things in general, if that makes sense.
