I read a quote on power yesterday. Here's my version of it:
"When you doubt your strengths, you give strength to your doubt."
You've been gifted with talent and skills for a reason.
Don't let misguided thoughts or other people's criticism squash them.
People need what you have to offer.
It's okay to accept that you're good at something!
You need to elevate your self to educate others; not in pride, but position.
If you see yourself as less able than you are, you have disabled yourself.
Trust what you know to be strong in you and put it to use today.
That is real power.
