It’s interesting that the GP says ‘success’ and you’ve said ‘wealth’. One of those Freudian slips that belies true intention. More often than not, wealth follows success, not the other way around. But to be 100% clear, success and wealth are not one and the same.
you need to own equity in something, instead of just selling your time
Even if it's just owning some index funds, equity in things that grow and compound over time is the easiest way to wealth I can think of.
