After I graduated, I started working after about a month. I don't regret it, but sometimes I wish I could have taken a break first before starting to work. You know, get the feeling of being college-free? Well, I still have my post board exam days as some kind of experience being a bum, I guess. Haha.
Anyway, the point is not to worry too much. Just take your time, think about what you've been doing for the past four or five years. Then, think about what you want to do in the coming years. It's always better to have a plan. List down your goals, plan how to get them, and then start working to achieve them. But as I said, for now, relax and enjoy your vacation!
