You’re not responsible for what others say or do, but you are responsible for how you respond.

You’re not responsible for your upbringing, but you are responsible for whether or not you stay in the past.

You’re not responsible for the standard of the work of the people around you, but you are responsible for maintaining your own standard of excellence.

You’re not responsible for how engaging or inspiring your boss is, but you are responsible for keeping yourself motivated and focused.

You’re not responsible for the attitudes of the people around you, but you are responsible for allowing yourself to be influenced by the right people.

Don’t get bogged down in things that you’re not responsible for.

You have a responsibility to bring your best work every day.  That should be enough.
