Anyone going to sign up to the italki 2015 wallet challenge? What reward are you hoping for from the inevitable wallet cramp? I'm going to try half hour sessions everyday to try and build up more conversational fluency. In general I speak too slowly, and perhaps I should be more strategic about what subjects I decide to talk about. Sometimes I decide I want to talk about something and then after some fumbling around I realise I have none of the required vocabulary for the subject!
