I find it interesting that you put "Dedication tips" as the name of this thread. I thought I was going to read about persons who had dedicated themselves to their path of magic or earth based practice Wicca or any other occult path.
Dedication is an intensely personal thing and signifies that you are ready to take your practice to the next level. It starts you on a path to creating a stronger relationship between you and the spirits, gods, goddesses or entities you work with.
Nearly all beginning Wicca books give suggestions about a Dedication Ritual. Scott Cunningham's book Wicca for the Beginner (I think that is the name, it escapes me and my last copy left the house a while back). There are some newer authors I am sure who cover it. You can also goggle Dedication Rituals and research it that way.
This approach might help you refocus on why you do magic and get you excited again about doing it.
