Hi, Lupa, welcome to PsychCentral (PC). I use my negative thoughts and habits to help me where I can by figuring out how to work around them. I could never read my textbooks because of anxiety so I switched to writing and surfing the Web about those subjects. Now I write better because of all that practice and I'm an excellent researcher and I got A's in my subjects when I was in school.
I do not know what your goals are but it sounds like you are concerned about time. I would think of ways to use time "differently", so you learn to do complicated math or accounting problems at the grocery store

or create a situation like Barbara Ehrenreich did in her book
Barbara Ehrenreich | Nickel and Dimed and deliberately do not-so-fun activities to get somewhere larger.
