We live in a time where we are often faced with struggle, despair, and heartache on a daily basis. Rather than focus on what is wrong, or what you don't have, or who/what has failed you, count your blessings. The things that we focus on will flourish while the things we discount and ignore will surely wither. So, even when there is only a drop of water left in the glass, focus on the drop rather than the void.
1) Be grateful for your trials; there is a lesson in them for you. You will become stronger and wiser after you push through to the other side.
2) Be grateful for the disagreements you have with others. Assuming that all parties are in their right minds, it means that everyone cares enough to keep communicating. If the problem hasn't been resolved and the lines of communication close, it could mean the loss of a valuable relationship.
3) Be grateful for all that people have done for you in the past, even when their hearts or ability to help have changed. For whatever reason, they chose to ease your burden during a difficult time. Cherish that and be sure to reciprocate it.
Keep your pen to the paper! Remember, inspiration is everywhere...
