Fun doesn’t happen all by itself.
You don’t get to have fun on a “just because” basis. You have to first open your heart or mind to something new. You have to indulge ideas and allow them to take you places without knowing exactly where they’re going. You have to humor people long enough to see if anything interesting lies beyond your expectations and assumptions.
And most of all, you have to try.
If a good time is what you’re looking for, then the last thing you can afford to do is adopt a “let’s hope it turns out fun” approach. Perhaps it’s true that some situations are simply not fun. Nevertheless, wherever fun is to be found, it can only be found because of your decision to get involved in the process.
Don’t just have fun. Look for fun. Create the fun.
