Just start. Make a splash.

There is no correct place to start. Wherever you do end up starting is likely not going to be the place you end up. Without starting you can’t end up anywhere.

Get attention. Do all kinds of stuff you haven’t tried. Find out what you like the most. More importantly, find out what your community likes the most. Somewhere at the intersection of your passion, skill, and ability to attract attention will be the start of something great.
