I really don't lije these "work hard in all your 20s" advice because I'm at nearing the end of my 20s with great results but I feel like I want to save what's left of my 20s instead of chasing more cash. I haven't personally met people who worked hard until 40s and felt like it was worth it for them. Being a successful person personally has always been way more than just having a successful career and money.
