Motivation is really about perspective. Most of us feel “purpose” when we train for something difficult or we feel our hard work will benefit either ourselves or our families. It’s important to frame your efforts in terms of how they will enable you to be the best version of yourself, so that you can in turn help others be the best version of themselves. In other words, if you can’t be motivated by an event, perhaps you can see yourself as a motivating/inspiring factor for others. They may decide to work harder at being better because you are doing so. But don’t expect to see the effects of your work: we often impact others in countless ways without ever knowing we’ve done so. Trust that by putting your best effort out there, you are having an impact.
