I would choose an artist!
First, I’m not really good at sports.
And second, I really like art!
Artist will be a nice job for me.
And also wanted to be an artist when I was young!
If I become an athlete, in the every single game, I‘ll be nervous!

“ When you spread a feast, invite the poor, the crippled, the lame, the blind; and you will be happy, because they have nothing with which to repay you.
For you will be repaid in the resurrection of the righteous ones.” — Luke 14:13, 14
