I Want Never Gets ....?

In the same way that you can target fixate and get tunnel vision on real things in space, so you can with ideas and goals.
Nothing wrong with single point focus, pure intent, clear purpose. Very useful and effective ...... Unless the very fact of 'wanting' creates a bridge for your opponent - Want something too much, and you leave a hook dangling out in space for them to exploit.

Baits only look tempting to those waiting (hoping?) for errors, because that is what will appear.
Openings seem inviting if you really want them to be there.
It's a fine line between looking a gift horse in the mouth and seeing something that is too good to be true.
The only true way to understand the difference is to watch, experience, and learn to differentiate.
To keep with the theme .... There may be no such thing as a free lunch, but some are definitely more expensive than others.
