Worry is not a sickness but a sign of health. If you are not worried, you are not risking enough.

Put your money at risk. Don’t be afraid to get hurt a little. The degree of risk you will usually be dealing with is not hair-raisingly high. By being willing to face it, you give yourself the only realistic chance you have of rising above the great unrich. Worry is the hot and tart sauce of life. Once you get used to it, you enjoy it.

Always play for meaningful stakes

Resist the allure of diversification
( Because it forces you to violate precept minor axiom 1 )
( Because it creates situation where gains and losses cancel each other out.
( Because you end up with too many balls in the air )

Always take your profit too soon.

Sell too soon. Don’t hope for winning streaks to go on and on. Don’t stretch your luck. Expect winning streaks to be short. When you reach a previously decided-upon ending position, cash out and walk away. Do this even when everything looks rosy, when everyone else is saying the boom will keep roaring along.
The ONLY reason for not doing it would be that some new situation has arisen, and this situation makes you all but certain that you can go on winning for a while.
Except in such usual circumstances, get in the habit of selling too soon. And when you’ve sold, don’t torment yourself if the winning continues without you.

Decide in advance what gain you want from a venture, and when you get it, get out.
