To be decisive is a good attribute.
Decisiveness: having the power to decide, being resolute, and determined, works whether you’re right or wrong in that decision.
If you make the right decision, great! It was fast and efficient and good.
If you make the wrong decision, you will make a new decision quickly to fix the problem. Because you’re decisive!
Those who are indecisive can do neither.
The inability to be decisive traps people in a sort of unproductive purgatory where bad things seem to happen all the time.
I tend to be the person who has evidence(or a strong gut feel) that a problem is heading my way, but I'll avoid making a decision until things get critical (i.e. the car finally dies after being on the verge for six months, or the refrigerator stops working after making a very strange buzzing sound for 2 months, etc... etc...)
Sure, you can solve most critical problems, but the wise man sees danger ahead and avoids it. He does it by being decisive.
There is a famous quote by Tommy Lasorda "There are three kinds of people in this world: people who make it happen, people who watch what happens, and people who wonder what happened."
Be the first kind.
