Is it worth it to save young?

I'm 21 years old with about three years left to go in uni. I've saved and invested 35k into stocks, funds, and HISA over the years and wondering if it's even worth it to be frugal in my early 20's since I'll be earning 'adult money' later down the line. I do spend lots of time with my friends and travel but I'm wondering if it's even worth it now? Otherwise, could someone give me some motivation to keep going? Thanks
