Often times we contribute our success to "luck". Luck is over rated. In my experience much of success is based on smart people, hanging with other smart people, at the right time (a great event) and then more amazing things are bound to happen.
So success is not RANDOM or LUCK.
It's doing a series of amazing things or experiences or smart moves that result in more great things happening. It's not luck, it's purposeful serendipity.
