Having already watched every TED talk released till date, 1100+, I keep scouting for other interesting ones. One good source is TEDx talks, which are independently organized TED events. 

Franklin Templeton Investments partnered the TEDxGateway Mumbai in December 2012, and have released a bunch of talks on FT Idea Caravan website. I went through each one of them, and this post is a brief summary of each talk. I've added my personal opinion at the end of the post.
