At my current age (25), I don't necessarily agree with this. I do understand the philosophy behind "work smart, not hard", but when I come across these posts where someone is claiming "work less, do more", i question whether they're truly passionate about what they're doing.

My personal opinion as a startup founder, is that there is no such thing as work/life balance. Your startup is your life and your work should contribute to it.

That aside, the post is rather misleading. You're giving advice to others on working less hours and smarter but had you worked smarter previously, you may have a different opinion.

I prioritize my health, take a 5 minute break every 25 minutes (pomodoro technique), and get at lest 7 hours of sleep each night, all things which you seemingly didn't do.

For now, all I can say is that I hope my competitors are reading this and nodding their heads.
