I ran git log on my main project this morning instead of writing code.

First commit is 1 November 2023. Today is day 1,038. There are 550 commits in it, spread across 103 distinct days. 935 days have nothing at all.

I ve noticed I m becoming much more careful with annual plans, especially when it comes to new AI tools.

The discount might be good, but the question in my head is no longer only, Will I still use this a year from now?

I keep a spreadsheet for our mortgage. Overpay early or invest the difference, that is the whole question, and I have rebuilt it maybe ten times.
Every version gives a different answer, and always because of one cell. Expected return. Change that one number and the answer flips. Everything else in the model is arithmetic I can check.
Runway is the same shape. The answer depends on a growth rate nobody knows, and the rest is addition.
The difference is that the mortgage sheet has no audience. Nobody sees it, so I never round anything in my favour. The startup model gets shown to people, and that is exactly where the definitions start drifting.
Do you keep a personal money model? And is it more honest than the one you show to investors?
