Expand beyond yourself, give of your time in charitable works. You now have the freedom of time and money and can change the trajectory of many lives if you are up to it. Life means more when it’s not just about ourselves.
The most important reason we struggle to motivate ourselves after a major success is that we fail to recognize the signs of burnout. So after small or big wins, don't become complacent rather think about ways how you can achieve even better results.
