I am usurping the copyright of a comment made on my blog earlier and adapting it here, because it is profound:
“Life is a marathon, not a sprint. Just because you are not shining today, does not mean you can’t shine tomorrow.”
Your time will come too.
And, above all else, be true to your heart. I could “shine” as CEO of an international Fortune 500 company and yet still be miserable and losing hair from work stress.
So, just make sure you are shining for the reason you want to.
