In part it is true,  our moods change our world view changes. But it's a bit simplistic as it assumes we are in control and there are no subconscious or unconscious forces at work in our psyche or external forces. That is why a lot of that 'positive thinking' stuff is garbage, it is fake positivity preaching, not the real deal. If it was so easy to do everyone in the world would be happy little munchkins. We are slaves to our hormones, genetics, environment and nurturing as infants.
Yeah it is absolutely true.what the mind perceives is showing in our actions.it is likely our mind is the master of our actions.so therefore  if we want to change our lives positively ,better to think positively and it will happen. disciplining our minds also is the other word to success.
