One moment of life is not worth your sadness.
Many people worry over things that won't change. Focus on things that bring one happiness should be the main focus instead of worrying over one's present situation and problems.
Stress only brings depression. Stress is like a heavy load, holding on to it will not only make you tired, it will wear you out. The truth behind stress is that it is better left unattended to.
Instead of focusing on problems of life and stress, why not just while away the time by making yourself a better person. Better at what you do, whether it is work, school or your careeer you might be into?
Life is not worth a moment of your sadness. Be happy today.
