We all know people that hang on to their suffering. You might be one who keeps their suffering like a mantle of protection. As long as it is in place, you do not need to take on anything new.
Do you know how much suffering will shorten your life span and your ability to see the joy in life? Probably not! And, you will wonder why happiness/peace/joy does not exist in your life. You see it around you.
That you recognize joy in other's lives is a good thing. It shows that you have not yet caved into the whole suffering as a way of life. Right now, it is only part of your life.
You have time to change, to move forward to the next phase of your life.
What will you choose?
