That's a great philosophy bro... The same philosophy works here As quoted by Henry Ford — 'Whether you think you can, or you think you can't--you're right.'. If you believe and think that you can achieve anything in life whatever you want will be within your grasp. If you don't know what sadness, disappointed feels like. They don't exist for you. If all in our brain the part we feed grows.
This would make you a human with issues...Words like narcissistic, psycho/sociopath come to mind.
Peace.
Well I was just making a point if you are depressed and you think in your brain "what is this? Why am I sad.. Being sad won't make things better. Things work out when you are happy and enthusiastic about life." and then you feel yes that's a valid point. It's all in your brain, the way you look at things. Nothing else.
Aha! ✌!
