Fun story:
The lead artist/dancer of
https://www.skyfirearts.com/ had had that dream for years, and that "first lucky break" came when (8-9 years ago) he was getting coffee and the guy behind him in line was
the guy for Tesla Coils in the US, who then helped Skyfire get up and running.
AFAICT, what's repeatable / helpful is a bit more nuance about "how to make luck":
1) Know what you want so you can recognize it when you encounter it
2) Give yourself lots of opportunities to encounter it
3) Have the self-direction and resources to jump on it when you encounter it
Of course, there's also just pure blind luck.
Edit: I know there's another step in here, but TBH I'd love advice for it: Making sure the other party recognizes you as something they've been looking for (aka, all the above but from their perspective). Advice?
