Regarding your purpose, it’s likely that the signs of what your purpose is are all around you.
It’s the thing that you think about when you’re bored.
It’s that feeling that you feel when you know something is wrong, and that you could do something about it.
It’s that notion that ‘hey, I could do that to, perhaps even better’ when you see someone else doing it.
Now, remember, these are signs pointing towards where to begin.
This is not a movie; a genie is not going to appear and tell you exactly what your purpose is.
It takes a little bit of practice, trial & error, and effort.
Actually, it takes a lot.
But you have to start somewhere.
