A commitment to one’s future self means investing in loss or failure here and now to accelerate progress. The more willing you are to invest in momentary loss and pain directed toward a goal, the faster you’ll adapt to the level of your future self.
If you want to become your desired future self, play at their level as quickly as possible. Commit at the level of your future self. Adapt at the level of your future self. Your current self is clearly not there yet and will therefore need serious training, humility, and feedback.
People naturally avoid investing in losses. It’s comfortable doing something you can already do. Winning feels good. But if you want to aggressively become your future self, then investing in losses is how you get there.
