<p>Here's a tip for everyone who's still in high school and continuously worrying about grades and standardized test scores. Obviously there's more meaning to the following tip than what has been written, but everyone should get the point.</p>
<p>Don't worry about things in the past, there is nothing you can do about them now. Don't worry about things that are happening now, make the best of a bad situation. Don't worry about things in the future, they may never happen.</p>
