Many teachers work in school for 8 to 10 hours and again after going home they give tuition classes to students for 2 to 5 hours. They get strain because of working more than 10 hours a day. apart from that they need to do their daily kitchen work and look after their childrens and huaband too. So doing online work instead of giving tuition and getting extra strain. I had given many suggestions to earn money in the previous posts also. Personally i would like to say about my wife, she is working only one hour a day online and earning more than 500$ monthly. some times she is not opening her computer for about a week, but still she earn money overnight, How is it possible? read my previous post- Click here
