I think you first need to recognize what your character in chess is, then you choose an opening accordingly.
I, for one, am positional, but very aggressive. - these things are considered to contradict each other, so it took me much time to find the right openings. Against e4 I play e5 - you need much memory but it's more fun than Caro Kann, French, Sicilian - I tried all three. Against d4 I was Very confused, tried almost everything. Eventually - King's Indian Defense.
As White - d4. [after playing e4 for 10 years, and c4 for 2 months]

Only if you try, sort of 'all of them' (not including the ones that look terrible to you) you can rest assure you have chosen the best opening for you. That's sort-of what I did. I tried everything, not including: Alekhine Defense, Pirc, Benoni, Slav, Leningrad Dutch, Bird, Polish.
P.S. The French Defense is a Great opening, it will win you Many games. But I stopped because you I think Black needs to be too clever / vigilant with his kingside, so I returned to 1...e5 - old faithful - go ahead White - gambit me!
