My dad taught me something that changed how I think about money forever. The Rule of 72.
For those who aren't familiar, it's a simple way to estimate how long it takes your money to double. Take 72 and divide it by your expected rate of return. That's it. Simple farm math.
What stuck with me wasn't the formula. It was the lesson behind it.
Start early, because time is your greatest asset. The sooner you start investing, the less painful it becomes later.
The moment I got out of college, I started putting money away for retirement. I wasn't exactly rolling in cash. Like many people, I graduated with student loans. I had bills and responsibilities. I had a million other things I could have spent that money on.
I also understood something important: Future Angie would either thank me or curse me.
The Retirement Mistake Nobody Wants to Make
Imagine waiting until you're 55 years old to start saving for retirement. Could you do it? Sure. But the amount you'd have to invest every month would be significantly higher than if you had started at 25.
Why? You've lost the advantage of time. Now you're trying to catch up. And catching up is expensive. That's exactly what happens with technology.
The Infrastructure Meeting Nobody Wants to Have
I can't tell you how many times I've sat in a conference room and heard some version of this conversation:
"We've been putting this off for years."
"The servers are old."
"The network needs attention."
"The backups haven't been tested."
"The ERP system is struggling."
"We know we need to do something."
Then comes the number.
Everyone in the room gets quiet because the investment isn't small anymore. Years of deferred decisions have finally arrived all at once.
It's the technology version of trying to fund your retirement in the last ten years before you stop working. Technically possible, but painfully expensive.
Most leaders don't ignore infrastructure because they're irresponsible. They ignore it because they're busy. Production needs attention. Customers need attention. Employees need attention. Cash flow needs attention. There are always more urgent priorities.
The problem is that aging infrastructure doesn't stop aging just because it's not in this year's budget. Servers get older. Networks become outdated. Applications become unsupported. Cybersecurity risks increase. Technical debt accumulates.
Quietly, year after year. Until one day, the conversation is no longer optional.
Technical Debt Has Compound Interest Too
One of the reasons I love the Rule of 72 is that it demonstrates the power of compounding. Small investments grow into something meaningful over time.
Technical debt compounds, too. Just in the opposite direction.
A delayed upgrade becomes two delayed upgrades. One unsupported system becomes several. One security gap becomes multiple vulnerabilities. One aging server becomes a business continuity risk.
The interest gets paid through downtime. Employee frustration, lost productivity, emergency projects, and unexpected expenses.
The Best Leaders Think Differently
The smartest CFOs and Plant Managers I've worked with understand this.
They don't wait for infrastructure to become a crisis. They build replacement plans. They budget proactively. They understand the lifecycle of their technology.
Most importantly, they recognize that technology isn't just an expense. It's part of production. It's part of business continuity. It's part of growth.
The goal isn't to avoid spending money. The goal is to avoid being forced to spend money.
Those are very different things.
Future You Is Counting on Present You
The reason retirement planning works is that you make decisions today that benefit you years from now.
Infrastructure planning works exactly the same way. The investments you make today determine the flexibility, security, and reliability you'll have tomorrow.
Every year you delay the conversation, the eventual budget meeting gets harder.
Every year you plan ahead, the conversation gets easier.
My dad taught me the Rule of 72 more than twenty years ago. What he was really teaching me was the value of thinking ahead. It's a lesson that applies just as much to technology as it does to retirement.
Whether you're planning for retirement or planning for business continuity, one thing remains true:
The best time to start was yesterday.
The second-best time is today.
