I think it's also worthwhile to consider not just whether you can amass several millions from frugal spending and steady-hand and sober-minded investments into the market, but whether you should.

I think most people set themselves goals such as working at FAANG, having millions in their accounts, driving expensive cars, not because it'd bring them happiness but because that's the societal expectations that they have unknowingly adopted and never noticed the switcheroo. It makes sense why society as a whole would value this "work to the bone at the cost of everything else" behaviour - it creates good workers whose work benefits the society. It is not clear how it benefits the worker.

At the end of the day, what's the point of having those millions in your bank account when your 75, have bad knees, arthritis and crippling back pain. Decide what you want to do with your life, and work your hardest to achieve that. Don't dance at the tune of someone else's fiddle just so that maybe at the end of that long ride you can get a handshake and a pat on the shoulder.
