A letter to a friend. (A task for the russian unified state exam in English)

Dear Stephen,
Thanks a lot for your last letter! Sorry I haven't written for so long. This month I'm really busy with prepairing for exams.
Great news about your sister! My best to her.
What qualities make a good teacher... In my opinion teaching the others and sharing your experience with them is very really great. First of all, this kind of of acprofession such as this demands human's qualities such as humanity, helpfulness and responsibility: one's responsible for to his students. For children a teacher becomes also a "parent" and takes a part in their education and raising.
If to speak about As for the professional qualities, they are: patience, steadiness, and competence.
It also depends on a the subject one teaches. For example teaching languages is good in particular for an easygoing and open-minded person: one's aim is make his students talk in foreign language without stress and shyness. What about hard science - one should be demanding e and rigorous enough for teaching such subjects as math, physics, chemistry etc. Actually these qualities are good for any sphere of teaching to a greater or lesser extent.
What about me as a teacher... One day I don't mind to teach the russian to foreigners. It seems to me a very interesting and good job. Meeting various persons, having every day not like another, sharing my experience and thoughts with others, arousing interest in Russian culture and continuing to learn myself. And what's the point - to see results of my work then. That's really important.
I didn't expect that you are fan of watching TV. What kinds of programmes do you like to watch? Sport, series or reality shows? Have you evere watched any russian channels?
Well, I’d better go now as I have to do my tasks in Italian. Take care and keep in touch!
Yours,
Daria
