Sometimes a thing just has to be done in less than ideal circumstances. And if it has to be done, just do it, and try to smile. The second you realize that you have choice, then the question is: "Who do I want to become?"
Nearly everyone overestimates what they can get done in a day, and underestimates what they can get done in a year.
Expect great things for yourself... we're all counting on you
Focus on becoming the person you need to be to accomplish the goals that you need to accomplish, to achieve the dreams that you have for yourself. Think of yourself as the author, not the character...
Your "self" isn't immutable. You aren't "a certain type of person". You are an evolving experiment. One that is certainly affected by the observer, and one whose outcome is affected by the inputs. If you want to carry something different in your heart, you can do that. You just have to want it bad enough that you can let go of the person you have been.
