Everyone at some point in life gets inspired by the words told by some great people or sometimes even words of an ordinary person or a movie dialogue can touch your soul. Some of the quotes which touched my heart to its deepest corners and motivated me to become a better person are:

Everybody has got sour memories from the past. It's upto you to carry them in a suitcase or in a small purse.
