Seth Godin has a post: I need more time.
It is a great post, short and to the point. I talked about this in the past.
Basically, you don’t need more time to make a decision, once you have collected a reasonable amount of information, just make the decision, take a choice and do it. As Led Zeppelin sang
Yes, there are two paths you can go by, but in the long run
There’s still time to change the road you’re on.
This tip alone made me so much more effective, and even better – less anxious.
