I think my goal on saving is about balance. You never know what the future might hold, so I am not particularly interested in the concept of saving (or delaying consumption), but I am not particularly interested in wasting money either.
When I first got my job, the income was lower, so we never saved any large sum of money (except the emergency fund), but we never go into debt either, regardless of the income level. When the income grows, our expenditure never goes with it, it just levels off. I still don’t buy expensive stuff because I don’t think it’s necessary or I don’t think I can afford it (my criteria is that if the cost adds up to more than 1% of my net worth in a year, I will seriously consider if it is affordable).
I guess overall I just have less material needs. I am content with all that I have, there’re nothing I force myself not to have in order to save. So I leave no regret if something happens tomorrow and all my savings vaporate. But we seem to find an optimal level of expenditure already and we just automatically save/invest the rest.
