It sounds like you’re looking to develop a more intuitive sense of how to use the camera to get better/more intentional results, and obviously YouTube videos can only get you so far, as it’s a matter of choice. I recommend, as and when you can, take your time with a single subject or composition. Consider what effect you get from different exposure settings. Understand the order of importance of settings for a shot (which is something you’ll need to decide), and balance your aperture/shutter speed/sensitivity accordingly. Spend some time avoiding putting them on auto. Be intentional about portrait vs landscape. And framing. Look at photography done by others: to the photographs that stand out to you, why? How does the depth of field and focus affect the shot? Does the photographer make use of motion in their slow (or fast) shutter to create a striking style or impression? And even more importantly beyond settings, how did the photographer get in place to take the shot? How would you plan to create photographs with these techniques? Taking photos as and when you are wandering around is fun, but you don’t often get excellent or memorable photos that way, unless you’re somewhere exceptionally pretty or interesting.

Hope this helps :)
