The most important test of how strong, humble and resolute you are comes when you need to respond to a trial in life. It’s how you respond to a test of your strength during and then after a difficult time has begun.
Sure, it’d be great to handle every test in life perfectly, but that’s not bloody likely. So when things don’t go how you had hoped, work on yourself so you respond to those times how you want to. You can collapse in on yourself and blame yourself, the weather, your work ethic, your intelligence, the economy or you can start the work at improving yourself.
Reflect, see what you did wrong and right, and work at improving it. Right now.
