When I was younger, I had this habit of collecting inspiring qoutes and had built up a commendable collection. Here are a few from the very top of my head.
Found this quote in an e-card I sent just now.
"May the most you desire be the least you recieve."
From Khalil Gibran's Prophet (I love that book):
"The lust for comfort murders the passion of the soul..."
From the poem Listen by Ella Wheeler Wilcox (my fave poetess):
"While life lasts, 'tis never too late"
My all time favourite qoutes:
"As long as there is breath in your body, never give up hope."
"Dont care what people think about you. Its what you think about yourself that really matters."
"Believe in the power of you"
