Never forget that you are one of a kind. Never forget that if there weren't any need for you in all your uniqueness to be on this earth, you wouldn't be here in the first place. [Buckminster Fuller]I confess that I pulled these two sentences out of a paragraph clearly intended to be motivational, about how one person can change the world. My take on that is, Yes, but a lot of the time that's not such a good thing.
Maybe I'm down on this kind of thing because it's one of those times when it's all I can do to live my own life, and not doing real well at that either. For instance, getting to exercise or getting to the eyeglass place to order some needed new glasses. Or . . . you get the idea. I don't need anyone telling me to change the world. Usually, when someone does tell me that, they want my money.
As for the above, I think that first sentence is a good one. But don't get above yourself thinking about your uniqueness. Every maple leaf on a tree is unique, different than any other. You don't need a magnifying glass to see it. We cat lovers know that every cat is unique and irreplaceable, though also catlike and not doglike.
The second sentence? ridiculous. I was not put on this earth to be born in September of 1942 because the world needed another crazy artist (it does make me laugh to call myself that, so indulge me); I was born because my father came home on leave in December 1941. Did they intend to make a baby? I never asked. But I know this - if they had an intention, it was to have a boy. Furthermore, I don't think God or a conscious manipulative universe sent him home on leave and made them be careless or set out to make a baby. Do you think it works like that? Really?
For me, after a few minutes on Facebook I feel most or all of us would do better to stop getting motivated to do great things and have some humility - to compare ourselves, say, to blades of grass. But we are blades that can jump up and down and shout, Look at me, look what I can do! That seems to get many people in a whole lot of trouble. I don't follow celebrity overdoses too closely, but they stream past me on the evening news. In the world of popular music, death from wanting to be spectacular is common. Uppers so you can give a pow concert; downers so you can sleep. I wish I could have said to Michael Jackson (for example), Really, you and your performances don't matter that much. Relax.
There are some things worth dying for, but being wonderful is not one of them.
(If you want to be wonderful, you could try to paint like this guy Charles Demuth. Though he didn't get there by trying to paint like anyone else, now that I think about it.)
