Depends on what it is. I want to reach the state of Nirvana one day and for that goal I have to let go of everything, of everything. I will be worth it, cause the end of suffering is my reward. Most people know the word Nirvana but they have no idea of the meaning or how to reach that state. Now it is difficult or next to impossible for me to let go of things that are dear to me and I am as well in no shape or form worthy enough for this highest of all goals but after 10 more incarnations I will be.
