I love to joke around and everything, but I often laugh when it's not necessary. By this I mean, I laugh at unfunny jokes to make the person feel better. I laugh at girls' jokes out of courtesy even when they're not funny before I can stop myself. I feel as though I'm not taken as seriously because I laugh in uncomfortable scenarios such as prolonged eye contact or confusion.

I just want to come across as more stoic. I know - fake it til you make it. But it's so engrained in my psyche that I just can't stop doing it. I'm making a huge conscious effort to lower it, but I need to know if there's any tips, tricks, or exercises I can do to quash this bad habit.
