Compound Emotion

Weekly essays on money, time, energy, and the decisions that compound over time.

For a long time, “I don’t have enough time” felt like a reasonable explanation for many things I wasn’t getting done. My days were full, my work was demanding, and there was almost always something else waiting for me. So I assumed the solution was obvious: become more efficient, organize the calendar better, and get through things faster.

But eventually I noticed something that didn’t fit that explanation. Sometimes I actually had the time. I just couldn’t use it very well. I might have an open hour at the end of the day, but not enough energy for anything that required real concentration.

I thought I had a time problem. Sometimes I had a different problem entirely.

The constraint can move

Earlier in my life, money really was one of my biggest constraints. When I came to the United States for graduate school and later started working, I had debt to repay, family responsibilities, and very little financial margin. Earning more and saving more solved real problems.

So I learned to optimize for it: work hard, increase my income, control spending, save the difference, and gradually build a financial cushion. That worked. But something interesting happens when one constraint loosens: another becomes more visible.

As my financial position improved and my responsibilities grew, I couldn’t solve everything by continuing to optimize for income. There were still only so many hours in the day, and not every available hour came with enough energy to use it well. The problem hadn’t disappeared. The constraint had moved.

An empty hour isn’t always a usable hour

I still see this in much smaller ways. Sometimes I’ll have an hour at night that looks completely free on my calendar. Technically, I have time to write, read, or work on something I’ve been putting off. But after a demanding day, I may have sixty minutes and very little concentration left.

An empty hour and a usable hour aren’t the same thing. My old instinct would have been to become more efficient: organize the day better, squeeze something else out, find another hour. But greater efficiency doesn’t solve an energy problem.

The scarce resource isn’t always time. Sometimes it’s the ability to use that time well.

This distinction seems obvious once we see it, but it’s easy to miss because different constraints can feel surprisingly similar. When we don’t make progress, the default response is often to add something: more time, more money, more effort, another system. But adding more of the wrong resource doesn’t remove the real constraint.

What am I actually short of?

One idea I kept returning to while writing The 7 Pillars of Wealth is that money, time, and energy are separate resources, even though they constantly affect one another. Money is relatively easy to measure, and time is visible on a calendar. Energy is harder to see, which may be why we often notice it only after we’ve used too much.

At one stage of life, money may genuinely be the constraint. Later, money may become less scarce while time becomes more valuable. And sometimes we finally create time, only to discover we don’t have the energy to use it.

A solution only works if it matches the constraint.

If the problem is money, increasing earning power or reducing expenses may help. If the problem is time, saying no, simplifying, or delegating may be more useful. If the problem is energy, adding another productivity system may only make us better at exhausting ourselves.

Sometimes none of these resources is truly scarce. We simply aren’t directing them toward what matters most. That’s why I’ve become less interested in asking, “How can I fit more in?” and more interested in asking, “What is actually constraining me right now?”

The second question forces me to diagnose the problem before trying to solve it. It also reminds me that the answer can change as life changes. I still catch myself saying I need more time, and sometimes that’s exactly what I need. But sometimes I’m trying to solve today’s problem with the solution that worked at an earlier stage of my life.

The constraint can move. The solution has to move with it.

P.S. What feels like your biggest constraint right now—money, time, energy, or something else? Just hit reply. I’d be interested to hear what you’re seeing in your own life.

What readers are saying about The 7 Pillars of Wealth:

“What stood out most is the emphasis on using structure and leverage to improve efficiency, instead of simply trading time for income. That perspective is crucial for long-term wealth building and made me rethink how I allocate my own resources.”
