What are the things that do not matter in life?

Social media notifications.

Luxury items. We’ll die, and you won’t take a pair of Rolex watch with you. Unless, you want to be cremated and for the record, gold’s melting point is 1945 degrees Fahrenheit. It will melt.

Your feelings. Less emotions, more logic. Don’t use feelings as a compass for your life. It’s not concrete or reliable materials.
Years. What counts is the life in your years, not the number.

Control. You can’t control the weather, terrorist attacks, other people’s opinions, or the news.
