Teaching is a very meaningful job and you can accumulate a lot of merits from it.
Teaching can help others grow in wisdom; at the same time you will grow in wisdom as well.
Shouldnt have the idea that you are the only one who is doing the right thing and that everyone else is wrong. Others can be doing the right thing but from a differnt approach.
We should learn to appreciate everything that happened to us, be it good or bad, as these experiences can teach us valuable lessons.
