A Little Motivation: Pain doesn't tell you when you ought to stop. Pain is the little voice in your head that tries to hold you back because it knows if you continue, you will change. Don't let it stop you from being who you can be. Exhaustion tells you when you ought to stop. You only reach your limit when you can go no further.
During our lives we will see a lot of pain, and we will see a lot of struggle during our times of growth, and times of change. I'm not saying that we should make an effort to enjoy the pain that we are or will go through, but we should always make an effort to go through it. The pain that we do experience, will be an experience that we will most likely remember for the rest of our lives, and it can be used to fuel the adventures you will take upon further in your life. With no pain, there will be limited to no amounts of gain.
