No matter how good or bad you have it, wake up each day thankful for your life. Someone somewhere else is desperately fighting for theirs.
Sometimes you need to distance yourself to see things clearly.
Don't think of cost. Think of value.
What you do today determines who you will be tomorrow.
Until you can see, and admit, that YOU are the problem... You will be unable to realize that YOU must be the solution.
Never do something permanently foolish just because you are temporarily upset.
