I got that idea from the great Grant Cardone.
The sentence it pretty self explanatory and pretty simple but simple does not mean its easy. Here a little breakup:
Commit first (say you will be there) …. figure out later (how you will actually get there).
Very few people do it because its pretty scary at first but its way better then to strategizing forever. This seems a bit contrary to the adivce most business “Gurus” give of saying no all the time. But when you think about it, especially when you are just starting out, saying no would kill many possible serendipity moments. So I dont believe in saying “no” as long as it is alligned with your long term goals.
