You have no obligation to be the same person you were yesterday. Hell, you don’t have any obligation to be the same person you were a few seconds ago. You can change anytime.
This can apply to your style, your beliefs, or even your actions. Do the right things. Be the best version of yourself. You can start anytime you want, and you can go at any pace your heart desires.
Don’t be afraid to be the person you were meant to be. Go do you!
