I think this would be an amazing way to get sponsorship and make money for charity.
There are similar things about on the internet, like the 21 day no moaning challange –
You should be able to nominate a spouse, a colleague, a gym partner or yourself and get sponsorship for charity.
This should definitely be a thing. Either that, or a 30 days of gratitude challenge. Gratitude is a life changer, try it for a week and see the difference that it makes. I think it would be a cool idea to take pictures of everything that you are grateful for, and make a collage out of it; that is then placed in a prominent place at home or in work.
Also, listening to this lego song helps too!
