You sound normal to me. Depending on what I am reading, often 30 min is the limit. If its general SF, yeah maybe an hour or so. I see in your writing a need to generate the UNIQUE. Playing music written by others, although providing joy to you, there is the need to create new music. I recommend, keep playing other music, when the time is right you will create your own. You learn drawing by doing, until you master it, do not worry about creating something UNIQUE. Since you like biking I recommend you take a 3 month journey by bicycle, it helped me a lot. But do not load your phone with games.
