As you continue along in your challenge journeys, remember not to sweat the small stuff.
I have literally seen people's entire day torn apart because they got cut off in traffic, someone took "their" parking spot, or someone said something at work.
Are we really going to let those small things stop our progress?
Of course not. Shrug it off and keep moving forward.
There are way too many more meaningful projects you could be working on. Focus.
