It's ok to not understand everything. Knowledge is no secret. Understanding is no mystery. However, all things are not meant to be known and understood by everyone.
We've all seen and heard of some idiotic situations and people. We've tried to understand how people could do/say certain things...wasting our energy. We've attempted to know all the angles, every possible problem...to protect ourselves. We've even, through our attempts to understand, tried to make things right or better.
Learn what you need to enhance yourself and those around you. Understand what it means, and what it takes, to use what you've learned to reach your goals and build your success. Distractions will always be there to soak up your attention...at the worst times; don't try to understand why. Stay focused and keep moving forward. Accept the true love and support that comes your way and climb your Mt. Everest until you reach the top.
It's beautiful to be you...with your determined self!
