It's all cyclical to me. One interest gives way to another during the course of the year. I'll go for long stretches on something than suddenly change, much to the detriment of my career. Luckily, I am now in a position where I am able to be creative, explore and problem solve and have all my interests addressed.
However, the one thing I have noticed that really draws people in (no pun intended) is when I draw. I have very few close artist friends. I occasionally get freelance work, but I prefer to work on my own art at this point and will almost never take a commission. I don't have much personal time, so I'm not likely to give it up for someone else's project. But, it's the best way I can connect with people. They see something that I thought of, something that I felt... and they react to it. I've always been pretty conservative with what I have shown, but I am slowly opening up. I need to open up more.
And, thus, I'm back at it. I admit though that I am a little creatively blocked. One great way is to find local drawing session classes. Some are inexpensive, some are extremely expensive. But being around other artists and feeling that creative energy can really kick start those juices.
I'm at a point in my life where I am looking back, and looking forward and it seems that the distance is the same. It's kind of scary. But I'm not done yet, and I have much to do.
