Feeling bad today? This will change. Feeling great today? This will change, too.
Understand that we live in a world, a universe that is constantly changing. No matter what, the one thing that will always be true as long as we live – everything changes.
Of course that can be scary. When things are going well we want to hang on tight. On the other hand, life's transitory nature means even the worst pain we feel soon disappears into the past.
So don’t worry! What you’re experiencing this moment will soon be over, and be replaced by something new. The trick in life is to know this, and not be so affected by changes. Just know they’ll always be there.
