It’s really hard to improve on nothing. Therefore whatever it is you want to get better at, you’ll have to start producing something.
With the constructive mindset, you can first start to see a feedback loop within itself: you will start seeing what is the value in what do. Secondly you can ask and get direct feedback from the possible customer even.
Important step is to do, the direction can always be altered. Produce something and incrementally improve on that.
