Think positive and positive things happen. Always remember things happen for a reason and we may never know; living in the present is the only way to live. ~ Tammy Myers
Acknowledge your sadness. Feel your pain. Only then can you move forward. Positive thought takes practice, but it takes you out of the negative and into a different world. ~ Mandie Jayne
Enjoy the little things in your life 
If you find yourself constantly trying to prove your worth to someone 
Finding someone who will want you 
If you did wrong, apologize for it
