Have you ever found yourself mindlessly checking your phone for updates, or playing some pointless game? In fact, do you ever do anything else, when on the bus or on the train, than sit glued to the screen? Research shows that the average person spends 23 days a year wasting time on their mobile phone. That's four years of your life!

These are more than mere time-killers - they are ways to unleash your creative side, to learn facts or train your brain; some will even set you on the road to happiness and mindfulness.
