One of my pet peeves is when some one asks what I do, I tell them that I own my own photography business and work from home and they go, "Oh, you're so lucky!"
Because actually, luck has nothing to do with it.
Intention, focus, hard work, tons of unpaid hours and determination however, has everything to do with it.
I don't believe in luck. I create my own luck, dag nabbit! (Boy I sure use the phrase dag nabbit a lot, don't I? Hehe.) I was not handed my job, I created it through a butt load of work and a decent dose or risk taking. Sure, occasionally some one might catch a "lucky break" to help them get further along but I can guarantee you that even the "lucky break" was a result of hard work.
