Yes, it's a very ancient idea.

"As we think, so we become."

- Buddha

Thanks, i was about to share the first pair of verses of the Dhammapada (words of the Buddha. … allegedly), which perhaps would have been better than the misattributed quote in my initial comment:

Mind precedes all mental states.

Mind is their chief; they are mind-made.

If with an impure mind a person speaks or acts, suffering follows him like the wheel that follows the foot of the ox.

.

Mind precedes all mental states.

Mind is their chief; they are mind-made.

If with a pure mind a person speaks or acts, happiness follows him like his never-departing shadow.
