The most valuable thing that anyone will ever give you is their time. Not their money. Remember that.
That's why I don't understand why actors become arrogant and are completely unapproachable - because as an actor, the most valuable thing you can do is talk to people and hear their stories, because it'll all come in handy.
It was a favorite expression of Theophrastus that time was the most valuable thing that a man could spend.
I think doing research is probably the most valuable thing you can do for any career you're interested in pursuing, and not just a career on YouTube or in media. Really take a look at people whose careers you admire and learning from their successes, but also their mistakes.
I think it's a very valuable thing for a doctor to learn how to do research, to learn how to approach research, something there isn't time to teach them in medical school. They don't really learn how to approach a problem, and yet diagnosis is a problem; and I think that year spent in research is extremely valuable to them.
Often, people think that individual data is the most valuable thing they can collect. But it's not useful to know what I am doing or where I am, unless you're particularly interested in me, which is weird. But it is very useful to know what a population of people are doing.
The artist-audience relationship is the most valuable thing, and anything you can do to fuel the long-term potential of that relationship is of value to you.
