Your success, or lack of success, is your responsibility. Even when you have a chain of command that you don't like as well, its your responsibility to work with the up chain of command.

Perseverance is also key to success in any endeavor, but without perseverance in combat, there can be no victory.

The temptation to take the easy road is always there. It is as easy as staying in bed in the morning and sleeping in. But discipline is paramount to ultimate success and victory for any leader and any team.
