Today, I try to be a farmer I prefer the title to be "Farmer For A Day"

There is a piece of idle land in front of our residential quarters. In the afternoon I went to the land there with my grandparents. This is my first time to do trying my hand at farm work. I fell feel that it's is really a hard work. We planted some beans, including mung beans, red beans, black beans and so on. We worked the whole entire afternoon. It‘s is so tiring tired.

That's why I was told to eat up every grain of rice in the bowl and let none be wasted!

Today, I tried (try might be appropriate if you wrote this beforehand) to be a farmer.

There is a piece of idle land in front of our home (residential quarters - while not wrong, this is really formal sounding). In the afternoon, I went to the land with my grandparents.
This is my first time doing farm work. I feel (fell is the past tense of "fall") it's really hard work. We planted some beans, including mung bean, red bean, black bean and so on. We worked the whole afternoon. It‘s so tiring. (unless you mean "I'm so tired").
