Suggested General Investment Approach

I am going to tell you a "secret" that seems so simple, that you won't be probably won't be all that excited about it once you read it, because it's common sense.

I have three (3) main rules of investing:

1. Only invest in things that you know.
2. Only invest in them when the price is good.
3. Trust yourself, and invest what you can in it.

This is true for EVERY type of investing, not only for stock.
