Make-up tips or something to help me be decent looking?

Hi, I really don’t like the way I look... but I can’t figure out how to make me look better. I don’t know what’s my main problem, if it’s my nose being long and beak-like, or if I have a weak chin, or a broad jawline, or a big forehead? Also I have bad smile/laugh lines I think. Like sometimes I think from the front I can look okay but like only in selfies where I see what I look like first. But I hate myself from the side and most they time when other people take pictures of me.
