You may have had unfair things happen to you, but the depth of your pain is an indication of the height of your future.
Bad habits are easy to develop but difficult to live with. Good habits are difficult to develop, but easy to live with. If you are willing to be uncomfortable for little while, so you can press past the initial pain of change, in the long run, your life will be much better.
I'm healthy as can be - not an ache or a pain. A lot of my prayer is thanking the Lord that I am healthy. I pray for long life and good health.
