But I feel that being able to get merit is very difficult even though there are several threads made for users who want to get merit with terms and conditions that must be obeyed.
Keep your motivation as good as possible because in my opinion your account is still as old as a corn that shouldn't complain about the merit system. You don't have to kick yourself too hard about merit because basically if you care about quality then merit will find you, not the other way around.
After all you have earned 13 merit so far since you started forum activity. This means that you are also a good poster so that some merit source or other users get your post. It's just that you need to be patient and keep working hard, but don't compare yourself with a number of other users. Keep your motivation and don't complain, but have a good pattern for your posts, it's really important.
