yeah, try to map. Someday you will send maps to others and they will say "yo, that should be ranked, cool map, I love it" then you realize you are good and quality mapper. But it takes some time. Give it a try, if you would like to map song, there is nothing hard to just try. I bet most of mappers started because they wanted to map one song that they like but there was like 0 maps on osu so they started mapping and they liked it - I mean they liked mapping stuff etc.
