What openings to play?

Hello everyone! I just got back into chess after being away for some time. Just wondering, what openings should I play and study? So far, I just play random openings depending on what I want to play. Even if my position is bad, I'm fine with that as long as I have some fun. With that being said, what openings are best for me? Thanks, Stephan

Thanks, I really appreciate the answer. I'll see what the opening is and will give it a try 

Anyone else?

"what openings should I play"
++ Simplest and best for world champions and beginners alike is
to defend 1 e4 e5 and 1 d4 d5 as black and to open 1 e4 as white

"and study?"
++ You should not study any openings at all. Just play and analyse your lost games.

"So far, I just play random openings depending on what I want to play."
++ That is all right, but stick to the same opening all the time, so as to accumulate experience.

"Even if my position is bad, I'm fine with that as long as I have some fun."
++ That is a good attitude.

Okay thanks!
