Going out for a nice meal with friends is an experience. Experiences are valuable. Saving a giant pile of money for your 70s and beyond accomplishes very little.
Sure, we don't want to ever run out of money. But we also don't want to avoid experiences in our lives to build up a pile of money in old age.
Enjoying experiences while you are young and healthy is important for a fulfilling life. You're going to have more fun with $100 at 25 years old than $100 at 65 years old, inflation adjusted.
Enjoy your youth and find a balance between spending and saving. Lifestyle creep absolutely can be a problem, but so can living so frugally that you avoid valuable and unique experiences.
