The End of The School Year

Today is the last day for the school year 2018-2019 and there will be a completion ceremony to be held at the gym.
I am not sure if I will continue to work for the next school year, so it may be my last chance to meet my students.
Yesterday, I prepared messages for each student and put each sheet in an envelop.
It took about ten hours to compose each sentence and write them on.
To be honest, I realized that teaching English is not my main role in school.
There are still many jobs I have to do.
I want to focus on improving my English skills so I might choose a different field for my job in the coming fiscal year.
