This is an interesting topic, and in my view, the key is not how fast you spend money, but being mindful and planning. Spending quickly is often seen as careless, but it can be justified if it goes into something valuable (not financially valuable but enabling precious experiences) or profitable. Spending slowly is not always wise either: money can be kept “forever,” and it loses value due to inflation.
Having some savings and saving up regularly makes sense, but perhaps keeping savings in fiat is unwise. Saving up for a nice family vacation or something like that is nice as well.
