To know how to do something well is to enjoy it. To that end, each of us must work for our own improvement and, at the same time, share a general responsibility for all humanity. I think when you quit learning, you're dead. Great opportunities are worth the risks. No trumpets sound when the important decisions of our life are made.
Destiny is made known silently.
We must not, in trying to think about how we can make a big difference, ignore the small daily differences we can make which, over time, add up to big differences that we often cannot foresee. This is the best job market we've ever seen, you don't have to settle. Be open and passionate about learning new things. If you can dream it, you can make it so. Like a muscle, it is strengthened by use.
