There’s many different ways to put this mentality of giving before receiving: give before you get, give more to receive more, etc. It all comes down to giving generously in order to receive abundantly, whether in work, friendships, charity or just life in general.
This article sums it up so well: Give Before You Get by Brad Feld (better than I can, so go read Brad’s post!).
What’s your take on this? Do you believe in giving more than or before you receive? Do you see this differently from the “no, you can’t pick my brain” belief?
