Giving up on your goal because of one setback is like slashing your other three tires because you got a flat. So giving up on my goals for succeeding school and graduating will not be stopped by one setback.
Sometimes the smallest step in the right direction ends up being the biggest step of your life. Tip toe if you must, but take the step. What great words of wisdom! Taking that first step is always the hardest. Fear is a hindrance. Step past it.
Just because you aren't given the credit and haven't been recognised for your work doesn't mean you have to give up or stop. You don't always need credit, other people do not always have to know what you are capable of doing as long as you do.
