One thing about a good strategist is that you pick your battles wisely, after careful consideration and analysis. You don’t jump at everything and dive straight into it.
That is not to say you don’t take risks, but you have the guts to say, “Yes, I am fully aware of the risks, and I can bear the consequences of not getting what I want, after all the investments.”
A strategist must have a clear mind, to think, to dissect information, to make analysis, and to derive answers.
If you cannot differentiate what battles to fight, perhaps it’s time to take a step back, go for a break, clear your mind, talk to people. When your brain is not cluttered, you will think better.
