We're programmed to constantly want to get better in every way possible, and no matter how hard you work or try you will always feel trapped because of your job, bills, taxes, loved ones. No matter what you have in life you're most likely going to want something else eventually.
But at the end of the day it's all the same, and maybe some destiny will be better than others, but theres no way to tell because there is only one reality.
Well yea. A big part of this "way of thinking" is heavily pushed by huge companies. They profit off of this by trying to sell the idea of perfection. That if we only had this product we'd be like those guys/girls on the advertisements. We'd look better, be smarter, be stronger, be more beautiful, etc. Companies really try to push this way of thinking down people's throats and it works.
