Falling Short..

Blagh, do you ever feel like despite your best efforts you always fall a little short... or maybe a lot short. I seem to be capable of dreaming big things, beautiful stories, awe inspiring images but when I attempt to bring them to fruition, I fall so, so short. I don't know that I find much else, more infuriating. On a daily basis I can't quite put what I'm meaning to say into words, but on a slightly less regular basis, I attempt projects that just fall short of what I was hoping for. Now, I realize this sounds very pitiful and a little like I'm whining, but it really does bother me on a pretty deep level. I do wonder though, if most of the time, the reason things don't look like they should, or when they don't on the first try, I give up out of laziness, and really, with a bit more patience I could make something half decent out of what I've started. But I also feel a little bit trapped by my lack of skill, I'd give anything to be really good at one thing, maybe drawing, painting, or even writing, to get across the things I'm thinking, not because I think they are earth shattering-ly profound, but because maybe it could help someone else understand what's going on in their mind, or help them understand what it is that's been eating at them.
One way I might convey the frustration, is I dream really vivid dreams, sometimes which play out like movies, and I wonder if they might have something to them that could make for a good story. But then when I try to write down what happened, or worse, try to tell someone, it just comes out lacking. Some movies have touched on fancy futuristic technologies that go into your mind and either link you to someone else, so they can move about in your memories. Or like in Start Trek with holograms, God I would give anything to have at my fingertips, some kind of program that I could slowly piece together ideas, talking it out, and it would lay them out in real form, and bit by bit, I could mold them into what it is I saw.
 Sometimes when I write like this it helps, but I still know, that all my life, I could write just fine, but my endings were always terrible. Even if the ending didn't matter, even if it was a summations of points already made... I could never get it flow just right... Maybe I don't want the discussion to end, maybe I want to leave it open-ended, or is it simply I just don't have the patience to bother.
