Write about your life, because you are satisfied with your study. Write some practical examples to show your learning status and happy feelings during the learning process.

Write down why you study happily. Learning makes you happy. What "factors" make you happy in your study?

You can also write that the happiness you feel is an individual experience? Or will everyone have an experience? Will it spread? Share?

Then end with a few slogan sentences, so that everyone can experience and fully enjoy the happiness in learning!

My composition is a bit too rigid. It would be better if I could write what I said without losing my liveliness.
