"Spheres of Influence". Control what is in your control (your actions, how you spend your time), influence what you can influence (encourage others to work hard, spend time wisely, stay longer hours), and try not to worry about the things for which you have neither control nor influence! This may seem obvious, but frequently time is wasted worrying/complaining about things that are outside of our control while things that could have materially improved a situation are neglected.

As a side note, if the team you're part of isn't a good fit for your goals and you have no options to change the situation, it may be time to look for a different team.
