Sir Richard thinks so.
And in my (considerably less) experience, I would tend to agree.
Decision procrastination rarely produces better outcomes and often makes what follow more difficult.
There are of course exceptions, and I've regretted making hasty decisions, too.
I find that setting a hard deadline helps cut off the oxygen to procrastination while giving enough time to think it through.
What works for you?
Even if things do fall short and the decision turns out to be not so great, you stand to learn so much more from making a bad decision than you do from not making a decision at all. After all, failure is life’s greatest teacher.
