  8. Life hasn't been good I've been lacking motivation. I realized if I want things to get done I gotta do it no procrastination. Plus you make learning fun especially when you ask us to solve it. It's fun when I get the answer. I'm gonna make my siblings watch it with me too lol. Have a good day, Khan

  30. I am going to go to britain and look for a girl their, more likely odds that my mother would agree to someone from the UK than the US..

    because from experience, US is a country made up of politicians. you can't participate in politics? you live a happy life, as single. the end

    but then… that means, no marriage!? 😐 there is this hidden genius for thinking out loud, once in a while… just leads to the results, that I wanted..

    results as we know, is the product of our efforts, which are based on our ability to think out loud.

    Prince charles married well, good for him.
