Promises - words spoken assuring that things will be done - most often lead to expectations. Periodically, expectations appear out of pure desire...without there ever being a promise spoken. At that moment, give yourself a reality check. Be sure, be certain, be most confident that you aren't expecting something outside of your reality.
Oftentimes, people get upset, angered, or hurt because someone let them down. Take the time to analyze and reflect. Did someone else let you down or did you let yourself down due to your own unfounded expectations? Do your best to be truthful and honest in your thoughts, intentions, and ultimately, your actions. Know who you are in every situation so you'll know exactly what (and what not) to expect.
Quell your anger, disappointment, and hurt. Evaluate situations honestly, with your eyes open. Make no excuses or whimsical possibilities...focus on your reality. Things do change, but not overnight and not without effort. Your expectations are your hopes and desires...not someone else's.
It's beautiful to be you...simply beautiful.
