Never give up!
"Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time."
Thomas Edison, inventor of the light bulb
I feel this holds true in so many things we have given up on, and never tried again.
This could have been letting someone steal your dream or lack of confidence! Whichever it is, your next try could be the time you have success.
Keep moving forward and you will attain your goal.
