Gravity: What it does causes more of it.
Gravity pulls mass together. The now-greater mass then has a higher gravity, which pulls more mass together until, finally, an equilibrium is reached when all the nearby mass that the gravity was strong enough gets.
Life is like this. It's easy to overlook all the details that go into building gravity. If you're doing business and you've ever changed over even a seemingly simple system, you know all that goes into it. Worse still is shutting down an area of operations without a smart transition - your gravity instantly gets weaker, and you stand to lose more than you bargained for.
The stronger your core, culture, your reserves, your systems, your mission, your customerbase, etc - the more you can stand a loss and a weakening of gravity. The flipside is that young businesses and movements are at serious risk if they lose some gravity -- the whole structure can come down.
The other way? It's joyful... when you don't need anything, it's easy to get everything. When your financials are outstanding, it's trivial to get lines of credit, investment at a good price, recruiting people on a performance basis, and so on.
This strikes some people as unfair. It's not unfair. It's just gravity.
