Through the majority of 2008-2010, my first priority was to sleep with the most, hottest women I possibly could.
It wasn't "work," "school," "get a perfect body," or "live a balanced lifestyle," it was all about meeting and banging women. You can only have one first priority.
I didn't even have a "job" for the majority of the time. Once I came to grips with that, I didn't feel guilty about it. There's a lot of worse things you can be doing than meeting/trying to meet women and sleeping with them. I learned more successful attitudes from meeting and sleeping women than I ever did in school or from any "internship."
I moved to a more balanced lifestyle toward the end of 2010 and didn't see much of a drop off in my sex life thanks to efficient screening and DTF hotties in social circles.
I don't necessarily recommend that everyone goes on a full-time "vision quest" or "mission" for pussy though. I usually suggest you meet women as a [significant] part of an overall efficient lifestyle, but I can't deny that you'll make quick psychological changes and get good results if you devote a good year to it.
