Your words ring true and I admire the courage you have to share such things in the public diary. Hindsight is a beautifully painful teacher. LIke you I have a similar story but unlike you, I didn’t have the strength of will to go on for as long as you did. We fall, we get up, we learn why we fell and eventually we do it again but without the mistakes of old.
You have done well to pinpoint your errors and building a corporate career in the field you love is the best antidote for the failures you’ve experienced. Indeed you are now more valuable to yourself and the world. The true test of a leader is the test of failure.
