Then I knocked on Rajabaht's door and good thing they let me in. At that time I've got a not so busy schedule and I used it to expand my network. I spoke to the people in my neighborhood and offered them my services. I made some flyers and paid shops nearby a visit so I could hand them the flyers personally. Only a few students made it to my home, though.
But I didn't stop. I made learning fun and easy for my students who came to my house. I introduced interactive and fun games I found online. I befriended them. I let them feel that I'm always around whenever they need help in their lesson. I also did the same thing to my students at the university and became close to my colleagues. I found out that those flyers I gave, those visits to shops meant nothing. Word of mouth is the key. Once the students enjoyed learning with you, they're the ones who are going to spread the word to others. Keep everything simple yet fun.
From 200 baht per hour a few years back, I am now getting a quite handsome rate per hour. I'm still not rich. I wish to be one, though. But teaching in Thailand won't make us rich. However, I'm proud to say that I'm no longer struggling. Also, I don't look for part jobs anymore. They now look for me. LoL
On a serious note, I hope this post will serve as a motivation to continue your fight. Don't give up just yet. I believe you won't be struggling forever. There's always a rainbow after the rain.
