6. You will be lucky and unlucky -In the fullness of time, you will be assuredly lucky and unlucky. And sometimes, things that appear to be bad luck will turn out to be good — the weak salesperson who turned down your job offer — or vice versa. You will have ups and downs, and you will win or lose things that you don’t deserve to win or lose. You will be unlucky and lucky, you just may never know when.
7. Avoid the myth and misery of sunk cost – See the item above about succeeding quickly. Don’t chain yourself to the anchors you lovingly create in pursuit of success. If it isn’t working for you or the business, let it go. Understand that it isn’t good money after bad money, it is all bad money. Fire that salesperson, let that manager go, stop selling that product, get used to moving on. You’ll make a lot of decisions in running a business. Accept that not all of them will be right.
