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.
Quotes: "Stop waiting for Friday, for summer, for someone to fall in love with you, for life. Happiness is achieved when you stop waiting for it and make the most of the moment you are in now." Be mindful, and live in the moment.
