Hello, I'm very happy in general and I always smile and laugh a lot, and I'm wondering if this can cause a bad effect on how I'm perceived?

It seems to be guys who have fun and enjoy themselves pull more and attract more easily, but at the same time it's cool to be the silent mysterious type, although that's not me.

So my question is, should I go against my personality and embody something I'm not or just roll with it?
