Finally, it's almost over. However, I've also learned a great deal. Just wait a little longer; it'll be finished soon. Then I can go for a ride on my favorite bicycle again. That's really nice.
In the future, I should organize the knowledge points on my own. This way, they are easier to understand rather than confusing. When presenting these points to others, it will also be easier for them to comprehend, rather than leaving them confused or unable to follow.
If they don't understand, it must be because I didn't explain things in a way they could grasp.
Indeed, one really has to keep learning, because while teaching others, one also gains a better mastery of the knowledge.
