5. Hand-Signed by The Founder of The Challenge
Every certificate is hand-signed by Dmitry Golubnichy who started the challenge back in 2015



100happydays started from the desire to help people find & celebrate the beauty of little moments in their everyday lives. It’s the same motivation that lies at the base of the creation of the official challenge certificate.


Conceptually & practically the certificate serves two main goals.


Celebration. Despite the challenge has been around for years, the number of people who manage to complete is still as low as 29%.


Reminder. While the challenge in itself serves as a “workout of your happiness muscle”, but the collected happy moments – as a reminder that, ultimately, it’s your choice. There is nothing that inspires better to be happy than seeing yourself happy, isn’t it?




All certificates are printed on the Arctic Paper in Scandinavia / Northern Europe.


Timeless. The paper used for printing the certificates is completely wood-free. Apart from the sustainability aspect, it ensures that your certificate will last for generations.


Genuine. Extraordinary printing demands extraordinary execution. The uncoated smooth surface with its natural white shade serves two purposes – it makes images genuine and alive while giving a very true natural paper feel.

In my life, I've been lucky to earn many certificates, but it's this one that I am the proudest of. As a matter of fact - it's also the only one that I 've ever hung on the wall.
The team was kind all the way through the order/shipping process. They were very professional and everything arrived to Spain on time and without any damage. Keep up with a good job!
What a great reminder after completing the challenge! I enjoyed it so much and now this poster reminds me of all the happy moments that I have collected. I will do it again next year!
The certificate arrived quickly and was even more beautiful than I expected. I have it on the wall by my work table in order to never forget what's really important in life.
I knew that my challenge inspired many friends to try it as well, but I really underestimated how many great - sometimes fun & sometimes deep - conversations this certificate started.
