You can’t compare your life with the quality of life of other people only, if you do so have the motivation to change something in YOURSELF.
Don’t let your fears come over you.
Get rid of addictions and harmful habits, develop habits that encourage you to move forward. Do this for at least 30 days. Psychological literature says that it is enough for a human being to develop a new habit for 21 days.
Forget the past and stop drilling back.
