To learn to make art you spend time working with the materials. That is it.
When the urge arises to judge the quality of your work, it will be tempting to say this is good or this is bad.
Take that energy that you might put into assessing the aesthetic and put it back into the materials instead.
Persist and grow. Avoid aesthetic judgements, and instead produce work.
Inevitably as you deepen your experience you will begin to autonomously develop techniques and content that you find yourself returning to.
As you progress through this process your style will begin to take unique, identifiable shape.
Through this process you will become a true painter.
Many people mistake technical capacity at predefined aesthetics as painting, but I would argue that this produces uninteresting work.
Every identifiable style was born from people who chose to work outside of preexisting style.
Goodluck.
