The instinct is: when I have the money and time, I will do the work, and then I will be the person. The argument here is that the order is reversed — you become the person first, which drives the doing, which produces the having.
The common sequence is Have → Do → Be. When I have the capital, I will do the marketing, and then I will be a proper business owner. It sounds sensible and it stalls indefinitely, because the having never quite arrives.
The proposed sequence is Be → Do → Have. Decide who you are being — an owner who prices confidently, a firm that follows up — behave accordingly, and the results follow from the behaviour.
Ziglar's version: *"You've got to be before you can do, and do before you can have."*
It is the folk version of identity-based habits — the argument that behaviour follows from who you believe you are rather than from what you are aiming at. James Clear makes the same point with more evidence in [Atomic Habits], and the [Identity Iceberg] is the same idea drawn differently.
