Other players really can't decide what openings do and don't work for you. First off you should determine if you're better at attack or defense and open, semi-open or closed games. Or at least determine what you like playing regardless of the results, and then go from there.
Start playing one opening at a time whenever possible, ie FD vs 1.e4 and QGA vs 1.d4. After every game (if possible) look up the opening in a book and/or the opening explorer here and see where you went wrong (or right) and try learning the lines a few moves at a time. If nothing else you'll start to get a feel for what variations you're most and least likely to face in your openings of choice.
This is the best advice.
I agree, but you should also study endgame theory before openings. In my opinion Caro Kahn defense variation tree is shorter than French defense but "shorter" doesn't mean "easier"
