It's true for any other field as well.
You don't have to take the face value of it, and apply your own learnings on top of theirs. It really breaks your bubble to listen to people who've had similar journeys.
When you explain someone why you did something, it kind of internalises within you too. You question why do you something is still the right approach. As we grow older, we tend to overlook many of the small new things which affect our work positively and become stagnant in our progress. Telling someone to go a particular direction keeps you on the edge too.
