You

The only reason to be disappointed in who you are is if you have expectations that you should be someone else, and that's not even possible. Those expectations almost always come from other people. Potential is a false suggestion that there's someone totally different inside you just waiting to emerge. There's plenty inside you and it will emerge and it will still be you, it's just the rest of you. Don't let anyone tell you that "the rest of you" could have been so much different/better. Only in the multiverse might you find a different you.

Just because others "see" something special in you and can't wait for it to be "realized", doesn't mean the process of becoming you isn't working. It's just not "working" on someone else's timeline. Being you is your full time job. Hang with those who appreciate who you are now and will allow you to become the "rest of you" on your schedule and avoid those who think you should/could/would be someone else if you just tried a little harder.
