It is really easy to just walk away. To say its too hard. Stay in the game, instead.
Stay strong when you feel weak.
Have faith .... courage + action + confidence.... and if you don't have it act as if do.
Staying in the game is trusting the kids will be ok, the dog will get fed, your presentation will get the job done, you will learn what you need to learn and will thrive the challenges.
The important stuff will get done. Believe in the good.
Stay in the game.
