I prefer to not ever "What if..." things. Sure, I'll consider possibilities. I'll hedge. I'll make sure that I'm prepared for contingencies.

When it comes to the action though? I prefer screaming "I regret everything!!!" and go for it.

It's never failed me. If you think it's time to go to an job interview with nothing but your pants on your head and a smile, go nuts. Maybe it'll work? The fact is, I've pre-regretted my actions so I don't have to worry about.
