laughter is infective

My husband passed this link to me yesterday for cheering me up.
It is really a great piece, from its design and the thought behind it.
After all, the restrained icy surface is not impossible to be broke. What one needs to do, is just keep laughing. But certainly, it requires a real determined mind and persistent effort, which is not easy at all. This is the quality that I am lacking of and I conclude that this flaw of my personality is derived from my little town commoner's mediocre nature. Not greedy and at the same time, one can not see any reason for striving as well.
