Why Learn at ALL?

I believe we live in age where we need to be asking the question “why learn anything at all”? Admittedly there many around the world who do not even have the opportunity to go to a school, we all need to advocate a change. But for those billions of us who have the opportunity to learn, we need to ask the question why learn? The truth, many learn to their degrees and Masters or even Phd’s for one main reason, to make money and have a better life. Not that these reason’s are not noble. We tell our kids study hard, or you might not have rice on the table or worst still , you’ll embarrass the family. Do we tell our kids “enjoy learning about the world”? Learn because you simply love it and you want to know more. In most places ladened with exams, we don’t have time for such silly notions! Well, I am a teacher, I love learning and I will continue to propagate the philosophy, “Love learning, learn whatever you want, whenever, however” Sites like Coursera just makes this much easier…

CourseraWe are a social entrepreneurship company that partners with the top universities in the world to offer courses online for anyone to take, for free. We envision a future where the top universities are educating not only thousands of students, but millions. Our technology enables the best professors to teach tens or hundreds of thousands of students.

Google Powersearch

Recently I concluded a Power Search Course offered by Google, and yes for FREE. We all search the web, everyday for various things. But are we searching and effectively and efficiently? Though I might regard myself as an pretty good “searcher”, there’s tons of thing’s I learned. And Google, to add  icing to the already free course gave a certificate of completion to everyone that completed the course., sweet!

There’s a great photo portfolio site at Be warned, all the pictures are amazing! I have my pictures up as well at (Check it out) Initially it’s a bit intimidating to put your photos up (at least that’s how I feel) as the standards of the pictures are really very professional. Occasionally it feels great to get a few words of encouragement from other photographers. But it’s an amazing site to simply see and learn. It’s free to register, although you can only post 20 images per week. However the subscription of $50 per year is not that expensive. Below you can see a thumbnail of my image named river vendor 01. Definitely something to check out if you are interested in photography. Warning: There are also nude images, but you can turn it off, not to have those images appear when you are browsing.
