I so understand where you are. This is our fourth year now without TV and I can tell you that I do not miss it. At all! I, however, used to procrastinate something awful and yes, it was because I was afraid. I can't quite pin point it, but at the time, I got absolutely nothing accomplished until I started finding out what I really WANTED to do. So then I started filling my time with old and new hobbies, friends, and now, a new business that is starting to grow and become successful. I can tell you now, not only am I much happier, but also I am accomplishing goals, feeling much stronger and I run out of time for all of the things I WANT to do in my day. There simply isn't enough time for everything I want to do. That is a good feeling and you can do it too! Also, I am a graphic designer,so I completely understand about the internet sucking the life out of you. I am on the internet a lot for business and some leisure, but as soon as I find myself getting sucked in I switch gears...like reading a book instead or making beer.
Start slow with a few things to see if you really like them then just wean yourself off the TV and internet. You will be amazed! I wish you the best!
