You are not wrong to think that Life is empty and meaningless. Note that you attach the meaning to life. The “why” is important as to your actions. Feel unburdened by needing to attach meaning to things. Sometimes shit just happens. Read Voltaire. Read some Nietzsche. Enjoy the emptiness. Put things and experiences that bring you joy into your space and you will find something that works for you. And just because it works for someone else doesn’t mean it works for you. Don’t worry about them. Their actions are out of your control.
