Have you just graduated from college? Hit your early-twenties and thirties? Feel as though you haven't "maximized your potential"? Does everyone else seem more successful? Happier? Does it seem like all the people you went to school with are married and popping out babies? Have they moved on to "important" careers while you're still trying to decide?
You're not alone. This community is for people who are in the same situation. Vent your frustrations. Discuss your options.
If you just have your own personal quarter-life crisis story to tell, don't ge shy. Feel free to post about it. Introduce yourself.
