Discouraged by reading bad news daily and with his marriage failing, Canadian Neil Pasricha  decided to try to focus on the positive and come up with 1,000 simple, free, awesome things, posting one each day on a blog.

Pasricha said his blog aimed to highlight life's simple pleasures, which were often taken for granted, such as finding forgotten money in a pocket, or fixing a TV set with a heavy blow.

Little did he realize his blog would strike a nerve and attract 40,000 people a day to join his discussions on how to enjoy the last triangle of a potato crisp, or the pleasure of laughing so hard that you cry.

Pasricha, aged 30, was amazed to win two Webby awards, known as "the Oscars of the Internet," something positive at a time when his marriage broke up and one of his closest friends committed suicide.

"I turned the worst year of my life into my best year by focusing on the positive. " Pasricha told Reuters in a telephone interview. "Every day I try to find something that is happy, free and universal to share, like the smell of a bakery or when a cashier opens up a new line at a store. "

Pasricha said when he began his blog in June 2008 he thought he might have trouble coming up with 1,000 simple, happy moments in life but now he is more than halfway through and ideas keep flooding in, from himself and from followers of his blog.

"These moments can start a huge conversation. Most of our life is really about hitting green lights on the way home from, or waking up before your alarm goes off and realizing you have more time in bed. But it is those small moments we forget about."

Despite the success of his blog, Pasricha does not want to change his daily life. “I travel regularly for an hour a day to work in the suburb. I like work because I like the people in my office. I’m not a writer and I don’t know how to use punctuations correctly. I just like observing the world and putting it down,” he said.
