About four years ago, one of my friend wanted to buy a camera. He ask me if he should by Nikon D7100 or Canon 70D. I told him you can buy D7100 and be happy with your choice, or check every advantage that 70D has over D7100 and regret your choice. Same goes for choosing 70D.

And same goes for life, one can choose an adventurous life style and focus on disadvantages and regret it. So... no regret (though one should choose wisely)
