“The men who try to do something and fail are infinitely better than those who try nothing and succeed.”
Words of reassurance to those of us who keep trying but at times don't feel like we're succeeding - we definitely are.
Which reminds me of the words of Thomas Edison when he was "advised" to stop trying to make a light bulb since he kept "failing":
“I didn’t fail ten thousand times. I successfully eliminated, ten thousand times, materials and combinations which wouldn’t work.”
