Cash
Cash is like air. If you run out, even temporarily, you don’t get to play another day. You must manage to ensure you don’t run out of cash.
It takes a lot of effort and forecasting to manage cash close to running out, without actually running out. So do whatever it takes to build up a cash buffer and remove the need to manage cash so precisely.
Buffer in place, and thus freed from worrying about tomorrow’s air supply, you can focus on maximizing long-term return.
A person prioritizing cash flow will try to avoid a big investment opportunity (a $10,000 equipment replacement, for example) that pays well in the long term ($2,000 savings per year for 20 years = $40,000).
A person prioritizing long-term return will rejoice at such “expensive” opportunities.
Create that cash buffer, prioritize long-term return and you’ll create a snowball effect as increased returns provide increased cash to fund even more long-term return opportunities.
P.S. This works equally well in personal life, business, and nonprofit orgs.
