Let me try:
Living a fulfilling life, reaching one's potential is very hard, we harbour a lot of evil in ourselves and are quick to do harm to others. What's to be done then ? Choose a set of values, a moral (and Peterson hints that the typical judeo-christian moral values are not a bad choice at all). Then strive to act consistently in accordance with those values but be always on the brink of learning something new, of improving yourself, of pushing the boundaries of your understanding of "good" and "bad".
I think these teachings could do a lot of good if they were applied by steemians. I think what many young people who jumpstarted the blockchain revolution (Dan Larimer included) failed to acknowledge that there is a fundamental trade-off between individual freedom and social welfare, that while trying to maximize the former, you reach a point where it comes at the expense of damaging the latter.
Freedom has a price and should have boundaries. My freedom should stop where your freedom starts. This implies that I need to always be open to notice the beginning of your freedom and stop there, not trespass...
