How much is too much?

My biggest frustration in life is wanting to do so much but not doing it. I often wonder if I simply want to do too much, with I've deduced is true but then I ask myself how much is too much? Basically I want to write, draw, paint, play, and pretty much just create in every single form of the word. I get frustrated when things that I start fall through because I don't like to be perceived as a flaky person. I've wanted to start up a clothing company again and have thus far failed to successfully do so. So rather than make my resolution to make progress in starting up a clothing company again and enjoy the work and time that I put into it. With that being said, I've come to realize that concrete New Years resolutions are just a fool-proof set up for failure more or less and before you peg me as a negative whining bitch, hear me out. Among the most popular resolutions are to eat less, work out more and spend less money; all of which were three of my original resolutions but then I got to thinking. Why limit yourself to such guidelines in life if life is about failing and learning from your faults? Although I do intend to eat better, exercise more regularly and be smarter about my funds, I will not do any of the three at the loss of my overall happiness and well-being. Like I said before, this year I want to make progress and become a better person through this progress.
