When you’re just starting in creative work, whether it’s writing or painting or music composition, you’re going to be unhappy with what you produce. What you create is going to be mediocre at best. At worst it will be a flaming pile of rubbish, unfit for the grossest landfill.
You should know, you must know, that this is normal. Every creative person goes through this phase where they produce inferior work. It takes time and persistence to grow out of this stage. It takes time and persistence to produce something good.
Whatever you do, don’t give up. Don’t stop creating just because you feel like your work is garbage. Don’t let feelings of inadequacy stop your journey.
