Do You Add Notes to Your Books?

Every three months after i finished a book, i will add a task myself to go and read my notes on it. And then one year after it, i also put another task in to go and re read my, my notes to the book. Asking myself those questions means that these books stay with me,. But rather than sot of going in, in through my eyes and out through my earst th, they sort of stay with me  and i kick them around a bit.
