Eckhart Tolle

People tend to dwell more on negative things than on good things. So the mind then becomes obsessed with negative things, with judgments, guilt and anxiety produced by thoughts about the future and so on.

Set your sights high, the higher the better. Expect the most wonderful things to happen, not in the future but right now. Realize that nothing is too good. Allow absolutely nothing to hamper you or hold you up in any way.

And I think that still is true of this business - which is basically research and development - that you probably spend more time in planning and training and designing for things to go wrong, and how you cope with them, than you do for things to go right.
