don't you mean put aside?
if you quit a hobby it's either because you have lost interest or that hobby is technically bad for you. I don't get why people quit hobbies if they still like them because they got work to focus on. I've had time for all my hobbies(working out, AMVing, video games, etc) even when I worked 100 hours a week because I enjoyed them. well oh well.. i guess on your free time it'll be totally focused on your goals and dreams and there will be no side time to even make a quickly video.
Hope you get time for friends, movies and other things you enjoy but assuming AMVs is just like any of those things me thinks you will not have time for any of those things.
well I wish you luck..
