"Why?"

"Why" things happen to us, that's a hard question to answer.

But "Why" we do things shouldn't be.

What fascinates me is that in poker, there's usually a game plan to follow. But most, if not all, of these game plans depend on the situation.  There is no set-in-stone rule of thumb. There's definitely mathematical reasons for doing somethings, and you'd be wise to follow them, but these often don't turn out as expected. In fact, computational game play is only most successful in the long run. In the short-term, anything is possible.

But what strikes me most is the sage advice "whatever you do, always have a reason for doing so. Be able to ask yourself why you're doing something. That's the most important thing".

And, like how poker is life, that's true in life as well.  As long as you have a reason for doing something, at least have a reason. It may very well be a bad reason. But at least you thought about it and can answer "why" for yourself.
