Welcome to the 10% Challenge! What is the 10%-CHALLENGE ? - The challenge is simple, easy and clear. You need to reach as many days as 10% of your P, PM, or PMO career, whatever you prefer. For example, if you've spent the last 20 years doing PM, then you need to accomplish 2 years, or 730 days, in this challenge. - You don't have to start your counter at zero and you need to post (preferably) everyday in this thread until you reach your 10%. When you reach 10%, you leave this thread forever. That's it.
