Wendell Castle’s Ten Adopted Rules of Thumb
1. If you are in love with an idea, you are no judge of it�s beauty or value.
2. It is difficult to see the whole picture when you are inside the frame.
3. After learning the tricks of the trade, don�t think you know the trade.
4. We hear and apprehend what we already know.
5. The dog that stays on the porch will find no bones.
6. Never state a problem to yourself in the same terms it was brought to you.
7. If it�s offbeat or surprising, it�s probably useful.
8. If you do not expect the unexpected, you will not find it.
9. Don�t get too serious.
10. If you hit the bull�s eye every time, the target is too near.
