Is it possible to save half your income? My friends told me that it is impossible as they spend a lot?

I think just like what everyone has said it really depends on your take home pay. The rest just depends on your need and your willingness to adjust your lifestyle to save.

I also have a few friends who are making at least 50k-60k a year who barely save 10% because they wont give up any of their lifestyles and spendings.

First, we need to understand what are we spending a lot from. For the diligent ones, they will be able to track their income and expenditure.

Then dissect it into needs vs wants .

Understand what does savings mean for the individual and what are the future goals that the individual is targeting .

No goals usually mean people will spend it recklessly or on their wants..

Totally possible. Extremely easy for 宅男😆.

Tips to save more. Need to earn more & live frugal.
Cut on fast food, bubble tea, starbuck all these are actually overpriced.

I'd say it's definitely possible unless your income is 1k
