Savings rate / Lifestyle (23m)

Hello Currently sitting at about 120k NW (including pillar 3a) and making about 90k per year. My salary will probably increase in the next years to 150k in 3 years (assumption) and still continue increasing after (assumption). I am living in a shared flat, have no car and also no girlfriend, but I go regularly on vacations with friends (but not very expensive ones) and as my savings rate is at around 50%, would consider myself more on the frugal end. I have no Car, Considering also "Zinseszins" on memories etc (referring to theory in book die with zero), I am unsure if I should spend more on Status items. Being young (23) it would be probably a different experience to posess those status items (cars, flat etc) than it will be lets say in 20 years, also considering if I would make like 500k-1m per year at some point, I wonder if I would regret "not have lived more" earlier as I have more money now and can afford things anyway. What are your thoughts ob this, how do you manage to find a right balance considering your situation between saving and spending?
