A thought on my mind:

When it comes to finances, time, design, etc … how much buffer is enough buffer?

For example, with liquid cash (USD in your checking or savings account) — how much is enough?

For example, it seems wise to get to the airport early. People say get to the airport at least an hour early for domestic flights, at least 2 hours for international flights. But for myself, I add at least an hour of buffer for each — 2 hours early for domestic flights (even though I got TSA pre-check), and at least 3 hours for international flights (also, we don’t check in luggage or baggage — only carry on). And the upside is that I actually like hanging out at airports — so I am able to get the upside of both. But a big lesson:

When in doubt, spend extra money to *NOT* have to go on that early-morning flight.

I prefer flights in the afternoon, so I don’t need to sacrifice my sleep in order to get to the airport early.

Back to the financial buffer thing

A simple thought:

If you don’t think you got enough financial buffer, you probably don’t.

And also with finances, when in doubt, add more buffer. Because having additional cash lying around can be a very good thing, for example, when Bitcoin dips you can buy more at a discount.
