I avoid this purposely. I did this a long time ago, I'd play 3-5, maybe even more games at one time, and I'd never get anywhere. I would pick one up for about 30 minutes and do nothing, get bored and move on to another, and then do the same thing again and again. Heck it ruined gaming for me at the time, I just wasn't involved in anything I played.
Now I strictly play more or less just one story-driven / single-player campaign focused game at a time. I have stuff like FIFA, Smash Bros, Mario Kart 8, and similar games on the side of course (although up until February I was without my WiiU so I literally just had a FIFA demo to play for a casual game I could pop on for a few minutes to relax with), but I'll only play one thing with it. I played FF Type-0 from September until about the end of last month, and now I'm playing Kingdom Hearts 2. Despite the size of my backlog, this works best and I'm actually not just getting through it, but I'm enjoying my games more this way. Give it a try OP.
