hating your work is def a bit of an exaggeration.. if chris ware really hated his work he wouldnt make it, he probably just doesnt like it after the fact. im not a big fan of my illustration work after the fact either.. and with time i tent to cringe at the sight of it, but i dont view it as a bad thing.
if you arent always happy with your work it means you are being critical of it and if you are that means you are growing as an artist. you may never get to the point where you say “wow im amazing” but its the adventure that matters not reaching your goal.
enjoy the fact that you are getting better, you dont need to love everything you make, but enjoy doing it and enjoy the fact that you are growing as an artist, thats really what matters most.
