I have been experiencing a similar thing. I have finally figured out that I have been bored with what I was trying to do. It wasn't exciting. I have started into some new things and finding some challenges, which is a good thing. I get off of work an hour before my wife does. I have been heading straight home and dropping all of my stuff off then firing up the computer and playing until she gets home. I usually get in an hour to an hour and a half each day now. If I am really digging into something I will stick with it longer. This has been helping me find some excitement. I am setting here spending time playing today as I took a couple of days off of work to just do whatever I feel like doing. I have been playing all morning, to the point of all four of my fretting fingers being sore enough that I need to stop. :)
I am working on some things that I am probably going to put out for the world to see and hear. That is my goal at least. I think once I get this going it will be easier. I have never really been one to like seeing and hearing recordings of myself but I am trying to change that.
