In every business there is always a path to success. So learn to keep trying to make it work. Be a hard worker who always believes in yourself. Do not be a person who always shelter behind other people.
Do not boast about your success because success will not last forever. And do not cry for your failure because failure will not last long. Do not end life just because you can not face the problem. If you do not need life, at least someone out there needs your life.
