Pugh's exercises aren't trivial calculations, they're the proof kind of exercise. If you manage to do 10 a day consistently and still have time for your other courses, congrats. I also don't think that people who develop new medical treatments necessarily did all the exercises in a pure maths textbook. Being able to prove that continuous functions on a compact set are uniformly continuous probably won't help you fight cancer.
