What kind of people are you surrounded with: the dreamers, doers or achievers? A simple model which I sketched to explain and understand people better:
Who are the dreamers?
These are the types who can talk. Those who want to learn to read music today and a foreign language tomorrow, but their desire to accomplish these never translate into meaningful action.
“I think, therefore I am.” — René Descartes
Who are the doers?
These are the butt of people’s jokes. These are the crazy ones who think different, stay different. They never lose sight of the fact that the only thing which sets them apart from other millions is they think and they do. And they don’t give up easily.
“First they ignore you, then they laugh at you, then they fight you, then you win.” — Gandhi
Who are the achievers?
These are the types who never, never give up; those who dream and do and are successful, but still manage to stay hungry, foolish and humble!
“Sometimes, if you aren’t sure about something, you have to just jump off the bridge and grow wings on your way down.” — Danielle Steel
