How can I be satisfied with my Job n Personal Life?

It seems to me that after you received your masters in Business, you gave up on yourself. You forgot how to grow as a person, make a goal and achieve it. You need to get back into that frame of mind and you will be happier down the road. You don't have to take what people hand you as a career. You have majority control over it - remember that. The girl? Getting into relationships at work are usually a mistake and now you recognize it. Learn from it and move on.
