It does not matter even if you work full time, go to school, need to go vacation, sick in bed, or even if you are in space, anyone can do this. Whatever you say not to try this system, it is just a excuse. Anywhere in the world, if you have one time access to internet, it's all you need.
Haijalishi hata kama kazi full time, kwenda shule, wanahitaji kwenda likizo, wagonjwa katika kitanda, au hata kama wewe ni katika anga, mtu yeyote anaweza kufanya hili. Whatever you say si kujaribu mfumo huu, ni kisingizio tu. Popote katika ulimwengu, kama una muda mmoja upatikanaji intaneti, ni wote unahitaji.
