Sometimes you have no choice but to be alone. ~ Shirley Bowles 

You came alone in this world & has to go alone so better get used to being alone. ~ Yas Chavda 

If we don't stand alone once in awhile, we don't get to feel proud of ourselves, feel that great sense of " I did it myself". That's very important in life to build strong character. ~ Brigitte Nicole

It make you a stronger person and with greater confidence. 

I have stood alone for so long and I don't need to test if I still can do. I don't need a man to prove I am strong enough to stand by myself. We all need someone to love to care for but not to rely on being strong and happier. Our happiness and strength do not depend on someone. ~ Norma Powell
