DON'T EVER DOUBT YOURSELF
You have so much to offer,
so much to give,
and so much you deserve to receive in return.
Don't ever doubt that.
Know yourself and all of your fine qualities.
Rejoice in all your marvelous strengths of mind and body.
Be glad for the virtues that are yours,
and pat yourself on the back
for all your many admirable achievements.
Concentrate on that which makes you happy,
and build yourself up.
Stay nimble of heart, happy of thought,
healthy of mind, and well in being.
-Janet A. Sullivan
Don't let anyone make you feel small. You are so much more than you think you are. Your power is right there in you. It's not in external things although people will tell you it is. Agreed that money, power, position have their uses too but it waits for the right person to take it to even greater heights. It is a willing slave to a worthy master. It will definitely need someone worthy to work it to good use or serve a better purpose. And you have the power to do that. If you see something which you must do to improve your life, other people's lives, or make this world a better place (which we all pine for), then do it. Don't wait for someone to do the job for you.
Believe in yourself... believe in you.
