Are you working to increase your attention span? 5 ways to increase your attention span - The Week Have you asked for help with your grades?

There's a lot of pride involved in learning new things and the rate we learn them versus how soon other people learn them, etc. but we all have things we are better or worse at, and different things we learn easier than others do.

If you want better grades, ask for help and work at getting better grades instead of hanging back and letting your self esteem take a hit from others. Self esteem is not meant to be armor but to help you continue to learn and grow for yourself.

That's what they wish they'd do for themselves but don't know how.
