Almost everyone I know is at that point where they're graduating, getting new jobs, getting married and the usual mumbo jumbo. I hope you all realize that this is it. This is the rest of your life and this may not always be a bad thing, you know. It's important to realize the worth of the moment you are in.
Please stop fretting about repeating summer semesters, they're just going to bring new memories.
Go for your Masters for all the wrong reasons. You need to make this last. Go for a job you love and keep experimenting with who you are. The rules do not define you, your creativity can get the best of you. Skip a day from work to sleep in or for a road trip with friends - it'll be more memorable than any presentation you have.
Stay foolish, everyone else wants to be wise. Make the most of your situation and be your own army, your own soldier and your own protection. Heroes aren't found, they're born. Be your own hero.
Lastly, love yourselves and live in the moment
