A particular thought persisted in, be it good or bad, cannot fail to produce its results on the character and circumstances.

James Allen (1864-1912), philosopher1

The mind is made up of thoughts which think themselves irrespective of circumstances. We call these thoughts important thoughts. For example if I think, ‘People are out to get me’, I may when walking down the street think that the people coming towards me are going to attack me, whereas in fact they may just want to ask for directions. Or if I think that, ‘Life is a disappointment’ then even when I achieve whatever it is I wanted to achieve, I usually find I am not as happy as I had wanted to be.
