Some luck lies in not getting what you thought you wanted but getting what you have, which once you have got it you may be smart enough to see is what you would have wanted had you known.
For me, every day is a new thing. I approach each project with a new insecurity, almost like the first project I ever did. And I get the sweats. I go in and start working, I'm not sure where I'm going. If I knew where I was going I wouldn't do it.
I try to make the good days great and take something positive from the days I'm not feeling good - work on technique or something like that.
