2 years training

Let me talk about my training which I have taken for 21 months.
I am paid to take the training of organic agriculture. I get about JPY150,000 for month, which is after tax and includes health insurance, unemployment insurance, welfare pension and half of rent. I have worked and learn in master’s farm 3 days a week. These 3 days are his shipping day, so that he needs a hand. In the first year it worked alright, as all I saw was fresh to me, but in the second year, it gets bored and I was not satisfied, as I felt master just needs labour for free, and he has not taught me the skill which I want.
However, this matter is settled when I reached a conclusion. He is an active person and I am a business man.
