Everyone is in pain
Pain is a sign that somewhere things are wrong and it tells you that they can be set right
Physical pain many times is an indication of a deep psychological pain
Pain is the precedent to change, for good or bad, who knows
Pain is progress
Pain is an option to grow
Pain is at times an indicator that you need to shut the fuck up and lay low
Pain at times makes things worse before they get better
Pain is a sign that you fucked up and if you get through this shit, you need to do better next time
Pain is your friend
Pain is a teacher
But, fuck, if you're in constant pain, go see a fucking doctor, cuz philosophy on blogs is much different from the hurt of real life
