I make a list of:
-All the options
-A list of pros and cons of each decision
-A list of assets I can offer each decision
-A list of liabilities that come with each decision
There is usually a clear winner. But sometimes there isn't.
In those situations you trust your gut. Yes its true. You cannot always think your way out of a problem. Sometimes you need to make a hard decision. I read that in the army, when faced with a difficult decision where the facts don't lean to either side, the job of the leader is to make a decision, based on what they think.
The key sometimes is just to make a choice, make one fast and then stick to it. Take ownership of the outcome regardless of what happens. Make it, stick to it and live with it basically.
