For me, if you believe in Bitcoin, keeping tabs on your fiat spending doesn't really promote long-term thinking. Surely it gets you back into fiat thinking instead.
I've always liked creating spreadsheets. Often, I do it even to help make the right choice (the pro's and cons) when choosing new tech - putting each product's spec side-by-side to help me decide.
I've also been involved with business accounts in the past - and was very good at it - noted by the firms that came in to check it.
However, I didn't lift up a finger to keep tabs when buying Bitcoin, for some reason it just didn't happen.
I'm guessing I didn't do this as doing so would concentrate the mind just on the very short term, and maybe be super cautious.
Has anyone else had a similar experience?
