Which of the two is better as a part time job!?

[M'Snah]

you have to deal with people all day long, who are irrational, moody, whining, don't understand a thing and blame the teacher for everything they don't understand...

welcome to my world ...

Thanks everyone for this generous sugestions

Now, teaching short courses of graphic desing seems easier and less stressfull and more friendly for me but(It won't lead to a good business - in my home town at least), while the sound engineering choice has a good potential of having your own business in the long run) I guess that's the main difference which I should decide upon.

Thanks everyone again !
