All you need to do is shed all expectations.
You have to be free of all demands.
If you don't want anything you will no longer need anything.
You will never have any pain to lose something what is supposed to be yours. What do you really need? A little bit food to live. A small amount of clothes to wear. A pair of shoes. A bed to sleep. And that's all.
Sunlight, oxygen, etc, are all free. You don't have to pay for them. Do you ever worry about not getting enough oxygen from nature?
No! Then....
Why do you worry about trivial things like passing the exams or the hike in your salary? There was life before you came here. There will be life after you depart this planet.
You don't know where you go from here. There is every possibility that your life might transform into a different version of life after the so called death.
Life is a process. Endless. Boundaryless. Sans Frontier!
It can not be, rather should not be measured by some years, hours, minutes or seconds. It is endless. It will remain like that.
You want it or not. Nothing matters. Then....., don't worry about our created little things like money, property, asset, funds, cars, etc etc.
Enjoy, be happy with what you get.
