5x5 Rule
In his book "Reinvent Yourself", James Altucher said:
>You are not just the average of the five people around you. You're the average of the five habits you do, the things you eat, the ideas you have, the content you consume, etc.
It of course doesn't work for everything, but in essence, if you want to be a writer, and call yourself a writer, well, you just need to write.
Wanna be a painter? Paint!
A developer? Coder? Programmer? Yeah, that too.
I think it ties really well with what I wrote a few days ago.
