Most of the important ideas for success are hidden in plain sight. However, they are often dismissed as simple and boring.
Health: take the stairs, and eat more veggies
Personal finance: don’t spend more than you earn, and save some for a rainy day
Relationships: treat others like you’d want to be treated
Losing weight: eat fewer calories than you expend
Learning: ask someone you admire what books changed their life; read those
There will always be someone trying to sell you something complicated. If it’s complicated, and has a price tag that makes you feel uncomfortable, it’s got to work, right?
However, it’s usually the simple ideas, executed well, that are the best place to start.
