When I started investing, I chased percentages. The returns looked exciting, until I looked at the actual amounts, and at the worry and risk that came with them.
I had logged every pound since I graduated and reviewed it each week. That log showed me something quieter: fewer Uber rides and Talabat orders, and a little more care when shopping, kept almost as much each month as my investments made. And it kept doing it, month after month.
None of this is new. Most good money books land in the same place: you can’t control much around you, but you can control your own habits, and habits compound.
Keeping that log by hand took hours every month, and it still never showed everything in one place. Lightning is the tool I wanted then: everything I own and owe, counted properly, so the habits are easy to see. It’s still early, and it gets better with every tester.
