How do I plan for life after my sports career ends?

You can manage the career you are in now. What frightens you is what comes after the sport ends, and that fear is honest, because for an athlete the end arrives early and certain. You are being asked to plan for a second life while still living the first. Almost no other career demands that. The fear shrinks when the after stops being a void and becomes a plan. Right now it frightens you because it is blank. The moment you put even a rough shape to it, an interest, a skill to build, a direction, it turns from a cliff into a road. You do not have to know the whole thing. You have to stop leaving it empty. So give the after one hour this month. Explore one thing you might do when the sport ends, and take one small step toward it while you still have time. The end is coming either way. Meeting it with even a rough plan is what turns dread into readiness.
