As others have said, poker will always be there. Your life won't be. If you have the ability to make poker your job, then its a different story.

I am in a similar position where my bankroll and abilities are at a turning point, where I can either get much more serious. However, I am also working my tail off making sure that I have a job when I leave the blissfully free land known as college in a few months. What this means, is that I am working around 40 hrs a week plus school, which doesn't leave much room for poker when I have a girlfriend as well.

If you aren't motivated to play, or don't have time, take a break. Just leave your bankroll there so you don't have to start over.
