There is a webisite 'onlinecardclasses.com' and one of the online classes is KickStart. I took this online class recently and it's all about how to KickStart your creativity mojo when it cannot be found. Their classes are very reasonably priced and access is available for life. I would urge you to check out the content of the KickStart class. It's hosted by Jennifer McGuire and Kristina Werner and, in addition to them, there are guest hosts who share tricks and tips that they use to kickstart their creative juices (one guest is t!m holz himself!). I got great ideas from this class. Good luck no matter what path you decide upon to get your creative groove back
Just for the record, I am not affiliated with onlinecardclasses in any way. I have taken a lot of their online clases and I just loved every one. I think the quality of these classes is outstanding and I mention them in the SCS tradition of sharing information.
