Namely transportation and giving proper workshops!
One of my adult students actually runs a cooperative business for taxis. In Malaysia, taxis are not really owned by companies. Taxi drivers are like entrepreneurs...they rent a sort of licence from a "taxi company" but they carry most of the risks of the business, and are quite invested in it (as you may imagine).
So my student asked me to come and speak at an event he organised. The main topic of the thing was "Improving customer service" and my role was to give a workshop on increasing their motivation to improve their English. I had a two hour slot and I rocked it! :) Not to say that it could not have gone better (it always can), but it just felt like being home! The participants were very much alike many of my former bus drivers, the atmosphere was in very much the same lines, and I actually managed to motivate people without even trying that hard! And I loved every moment of it!
And this is how the universe reminds you of what you're supposed to do with your life. And this is me being all energetic and stuff :)
