Thanks to MoneyWeek magazine for picking these.

Pound Cost Average your whole life and you’ll beat anyone who doesn’t

Only invest in things you can explain to a six year old

Every five to seven years people forget recessions happen every five to seven years

You’re twice as biased as you think you are (four times if you disagree with this statement)

Read more books and fewer articles

Read more history and fewer forecasts

Why visit your doctor once a year and check your investments once a day?

Be careful when reading how stupid investors can be and not thinking about yourself

Your circle of competence is smaller than you think it is

You’re only diversified when some of your investments perform a lot worse than others

Keep reading MoneyWeek! (I added this in as they’d only flagged nine!)
