Actually I wanted to study it too, but things went much different as I expected. So I just practiced with
PS a lot. A few weeks ago I started to use blender also. In the very first moment I was really confused about the Interface and i was about to forget about it, but then I remembered how it was with PS. I still remember all the buttons and I didn`t know what will happen if I try them. But I just did. Sure at first it was just like pushing some buttons and wonder how I got that nice effect in the picture and didn`t find out how to get the same effect again. Later I found out that there are many tutorials in the web and I tried some. So I learned new things and very often a much faster and easier way to get the results that I wanted. And now I think I already learned a lot. It is a lot of fun and everytime I look at my work I know that I can do things now where others had to visit classes. I think it is great to know that you can learn a lot of things by yourself and get good results, even if you also know you will never stop learning more.
Looking back to blender I still feel like I did when i started to learn with PS, but I am sure that I soon will understand it better. It will be a hard way again but I am already curious what i can do with it when i am better in it ... no matter how long it will take.
