I've been working out how to focus and get things done for about 25 years, mostly by getting it wrong first. At 24 I was working 12-hour days and still couldn't catch up.

On A Balanced Life I share what works for me now. One must-do thing a day. Planning at about 80% of my time, so there's room when things go wrong. Home and family first, then work, then everything else. It's not about hustling. It's practical stuff you can try tomorrow and keep if it works for you.
