Do you ever talk to yourself?
This is the only thing which I do for my own entertainment. This is something which is easily affordable and you are not creating a nuisance to others by talking to yourself. It all started during my school days when I was unable to draw the attention of my classmates. To stay busy, I started talking to myself. Some disciplined scholars of our school thought that I am a fool and falthu. Hardly they knew I was pursuing a self-made course to sharpen my skills. Thinking and always thinking.
Today the same friends are happy to spend times with me.
