I don't know Trevor Milton. I have never met him. Maybe he isn't a compulsive liar but just got in over his head and was trying to make it work. But I know I would never invest in something he is doing.
He obviously thinks you should learn from your mistakes and that you must be an avid and quick learner.
But learning skills is not what introspection / dwelling is.
It's spending times on thoughts like "what should I be doing with my life". "I can't believe how much of a victim of the system I am".
And he specifically contrasted it against doing stuff.
Writing code >>> walks in the woods.
Obviously reflection is necessary to recognize mistakes of the past. What Andreessen was talking about that you should spent majority of your time acting not reflecting. Not that you should spent 0 time reflecting.
It's surprising to me that you consider these equivalent.
Introspection is a process of discovery, to uncover a deeper cause why you did something.
Dwelling is when you can't let go.
Introspection is important. Dwelling is problematic.
How else do you decide what to do?
If you're wealthy time and personal energy are the most valuable, irreplaceable resources you now possess. Why squander them on fruitless, random pursuits if you could think strategically and do something that really matters?
Theyre not exactly wrong
I have followed Trevor for many years. And I think anybody who has done the same will tell you, lying is very very central to his inner core. He lies even when he has zero need to. He just cannot help himself. It satisfies some inner need.
The social taboos of cultures around the world are fighting a ceaseless battle to reign in these endemic outliers.
