Nature gave us pain as a messaging device to tell us that we are approaching, or that we have exceeded, our limits in some way. At the same time, nature made the process of getting stronger require us to push our limits. Gaining strength is the adaptation process of the body and the mind to encountering one's limits, which is painful. In other words, both pain and strength typically result from encountering one's barriers. Ray Dalio
