Take a notebook, notebook, notebook – like that. Write the header: "What do I need in this life?" Write all thoughts, ideas that come to mind. Perhaps the first thoughts will be quite or they will seem not worthy of attention. Still record. Nowhere in a hurry. A serious question.Write all. Ranging from supervised during a trip to the store phone and ending the great achievements: to learn a foreign language, get another profession, to marry or get married, build a house, to achieve fame, etc. do Not limit yourself to 20-30 points. The more you write, the better.
