What should I do to understand complicated artistic concepts better?

I am not a pro in art and design but i have been drawing as a hobby since childhood.
So to better your art try to first learn something about what is to feel any animate or inanimate objects with your heart and to do that you have to have a clear concept of what art is. Because Art is connected with beauty of your heart. So try to read some books first like of Anatomy for the Artist by Sarah Simblet, Drawing People by Barbara Bradley etc . And then take it a one step a time. My believe is 'Understanding is essential in any subject of learning' . My suggestion is also journey to the monumental sites , archaeological sites , best built church or building , mountain or spend some time in parks if you have time. They will always be your first teacher in Understanding your desire.
