Do You Have Any Regrets?

If i had a regret, it's hard. It worked out so well for me. My life is so good, i am reluctant to answer any questions about the past and changing it or regretting it. But a partial anser to that question is, i wish i had learned how to sell earlier. So i was forced into the job of head of sales and marketing as we were running out of cash in 19 19 82. And grew revenue from zero to a million a month in two years - then we went public. That was my contribution. But had i been better at selling before that, life would have been easier.
