The question is, what are you here to do?
Some discover this earlier than others.
The answer will evolve over time, and become clearer the more you test new things out.
So, if you’re completely lost and unsure of where to start, start with ‘what are you here to do right now?’
(Not ‘for the rest of my life.’)
Just as a child learns to walk by putting one foot in front of the other, taking a few risks, and via the occasional fall, so too will you discover your purpose.
