HERO?????

I encounter these situations a lot when I'm just a bit over x10bb in level 3 and I have a decent enough hand in late position(i.e. Button or Cut off). My thinking goes like this, If I bet x3bb this will leave me shortstacked + I probably have to bet the flop even when I miss. So, I think I'm better off going all in preflop if I'm raising. But is this really worth it for 75 chips?

How do guys play in situations like this?
