Most people overlook a truth, that is, many things do not need to be meaningful. Eating, drinking and having fun do not mean wasting time, and hard work does not mean extraordinary significance.
When you are anxious and mentally exhausted, please remember that life is the superposition of various experiences.
As long as you want, you can do those seemingly meaningless things, such as daydreaming, watching the sunrise, counting stars, sitting on the grass all day... your experience is the meaning.
Life does not necessarily have to do things that everyone thinks are meaningful, nor does it have to live according to the mainstream values of society, such as getting married and having children in your 20s, and having a car and a house at the age of 30. These are the meanings given by others. Whether to execute them depends on ourselves.
Everyone comes to the world for the first time, and the meaning is given by ourselves. Life is a wilderness, not a track. As long as you enjoy it at the moment, your life is meaningful.
