It might be you...

Be grateful

Most of the things we complain about are luxuries. I know it doesn't feel that way, but it's true. When I feel myself starting to complain too much, I remind myself of this. So many people would love to have that as their biggest problem.

Bend, don't break

Rules are there for a reason. Yet, they are also in the way of progress, safety, or completion of the mission at times as well. There's times to follow, bend, or break them. As a leader, there's also times you need to bend your style to match the dynamic movement of the situation you're in. All of these are skills that you can learn.

Apologize for access?

Personally, I think a true apology doesn't come with words, but actions and change. Sometimes the words are also needed. Just be sure they are followed by change still, otherwise it's just an attempt to restore access.

Choose the day...

You don't control outcomes, but you so choose your attitude, effort, and response to things that happen along the way.

Focus on the fundamentals

When you get tired, slow things down internally and stay focused and the most basic parts of your task. It will carry you way past where you thought you would fall apart.
