There must be 10,000 lists like this… let me add mine – hopefully with many useful twists.

1. You need to know what you are looking for – both to enter the market and to exit.

2. You need to know what the variations on #1 are – and what they are not!

3. You need to know what is imprecise about what you are looking for – it is more than you think.

4. You need to have thought about the imprecision long before you sit in front of the screen and certainly not just as you push the button.

5. You need to know what it will feel like if you turn out to be wrong.

6. You need to know how you will handle, manage, learn from and deal with that feeling.

7. You need to know what it will feel like if you are right – and again, how you will handle, manage, learn from and deal with it.

8. You need to know how to operate on the premise that “perfect is the enemy of the good”.
