There's something about chronic illness that changes you, and not only because it changes your physical health. Rather, it makes you realize your mortality and weaknesses. In that, you begin to appreciate the smallest of victories and the simplest of moments. Suddenly those days and events that once seemed like the end of the world don't seem so bad, because there are much worse things to worry about.
It's sad that we can't learn that until the irreversible illness happens. Those who understand without becoming sick are the truly blessed.
Treasure each moment that you can do what you enjoy. You never know when it will be taken away, nor do you realize how good your life is until you can no longer do the simplest of tasks without effort or not at all. Do not take anything for granted--not a breath, not a blink, not even a smile. Make changes for the better before you must learn the hard way that it could all be taken from you. Learn to appreciate every gift of your life.
This is what I wish I had more fully understood before getting sick. Just think what our would could be if everyone was thankful rather than envious and generous rather than greedy.
