Fix Your Faults Before Fixing Others
It's easy to see the shortcomings of other people. We think, if they just did this or, if they changed that, things would be so much better. And that may be true, but have you thought about what you can change about yourself?
Even if you're not the one "causing the problems" there are probably steps you can take to improve the situation. Look at every possible angle and search deep how you can support and lift up others on the team. You might just find they begin making positive changes as well.
