How to remember my mobile phone number
It made me
very proud of myself 
"10 numbers in 10 seconds"
How I did it: I used 43things.. I got a reminder with my phonenumber everyday and I would just recite the number to myself everyday (when I was checking my email).
Now.. after 3 months.. I know my number even when Im really drunk.. which isn't necessarily a good thing I have found..
Lessons & tips: Just check your mail everyday
Resources: 43things and gmail..
