It reminds me of my time in the Army. We would always [I mean always] conduct an AAR (After Action Review). There was no rank, nothing off limits and most importantly no feelings. Anyone could comment on whatever it was we just finished doing.

One phrase that has really motivated me is "be a lifelong learner". I don't remember where I heard it, but I identify with it. I don't know where I picked up my desire to learn (no pun intended), but it is something I crave now. I hope that it never fades.
