Quit my job... what next?

So I graduated from college last yeah. I only came out in my final year. I still have steam to blow off and need to find myself/ have fun/ go wild.From working I have about £10 000 saved up and want to travel and party, but also feel like I've achieved something. I've left my job and have about six months until I'm joining the military.Any ideas/stories for what I could do?
