You don’t need to make your entire life a challenge. But at the very least, try to always have something going that stretches you!!! Have fun with it. Maybe something that makes you wonder if you’re actually going to be able to do it. Maybe that’s a project you initiate at school. Maybe it’s learning a new skill and applying it in your lifestyle. Or it could be something outside of school, like organizing a fundraising event or even climbing a mountain.
Have fun with it. Live a little.
