The forum website requires a lot of getting used to and for someone who is a beginner in this forum It can be very confusing. I got discouraged too, but I found the courage to come back. Find the courage to stay, and it will not be long before you are able to understand really how this unique website works.
I would say that you should not be too focused on starting too many topics and that before you start a new topic you should use the search option to verify that a similar topic has not been discussed because many things have been discussed already in this forum. As a newbie, reading will do you very much good.
