Chillaxing

I can be very laid back sometimes.
Painfully so actually. So much, that sometimes people actually get annoyed at me because I don't take things very seriously.

I would love to tell you why I don't take certain things seriously, but I can't honestly say.

However I do know that I'm not laid back when I think about things that don't matter.

Such as whenever I don't know where to go in town to have my lunch, I'm like:
"Fucking hell Conor, just choose one you prick, Boot's or Urban Pie."
And I stress.

However when I'm questioned about which University I'm gonna go to to spend the next 3 years, I'm like:
"Meh, not too sure yet."
Therefore I don't stress.

Now is this because my brain has learnt this laid back'ness as a stress supression method, or is it a bit of an idiot move?

Would I be better off stressing about the bigger decisions, and not caring about the littler ones?

Or is saying fuck it to bigger decisions a better way to go?
