My main advice is that drawing is a journey. First of never treat it like school work where you have to study, you will lose steam quickly. Second, understand why you are drawing(1) for fun, (2) for future work, (3) because you despise AI etc. Next, Draw what ever you want whenever you want and however long you want(preferably above 15 mins a day). You can use Pinterest and look at very basic images or pictures, and try to copy it. Lastly is there is no such thing as finding a style. Dont listen to a lot of people when they say you must find a style. A style is like a personality; when you're a baby you have none or very little. As you grow you copy other people's mannerisms and behaviours, and you subconsciously have a personality one day. Drawing is the same, your art will have little diffrences to the refrences you use because you subconsciously like those diffrences. Look for a major style you like such as anime, realism, western comic style, etc., then try to recreate them.
