Am I really invested?

I recently re-activated my real estate license thinking that I wanted to do that as a side business. I got my license years ago but let it lapse because of challenging life events. I was so excited to re-activate my license and really make a go of it but I have been dragging my feet and not going after it.

How do I tell if I’m really not interested in the real estate business or if I am just being scared and lazy?
