Have i lost it?

Past couple days i have been looking trough my old sketchbooks  from my a levels and foundation level and even from 1st year in university and it seemed that they are more interesting more creative more experimental than anything i do now . Just had this like  a sudden realization that maybe im not as creative as i used to be. Like i now have some kind of restriction despite being more free to do any work i want. In some sense i understand why im not too keen on it. And well that is cos of the hatred towards uni but same time shouldnt that be the place where i actualy express  my feelings into? I cant exactly make my self be relaxed and do work lol . But i think my plan of action is to get a good size sketchbook no a5 nonsensse and start doing it for my self not for uni not for selling and  ot for anything else. Almost out uni anyway sobe plenty time to concentrate on it . I tnink main thing is to get the  mind motivated and be ok
