Bro, don't quit PhD - its just that you are not seeing the light at the end of the tunnel (no one sees it at the begining). This program itself is a life training experience. Once you go to conference you will start to see the possibilities. Now is the time to burn the midnight oil - trust me, you're not that far to kiss the last step of success.

For now you just need to get laid, that's all....just kidding.
