The summer break is almost over. Am I ready to re-open my shop?

Summer is just about over and I will soon be opening my shop again. I'm looking forward to it yet I'm a little bit hesitant as well because I don't want to get wrapped up in the "selling as a measure of success" mentality. I have found that I've been a lot kinder to myself these past couple of months and as a result, I've been happier. I've been spending my time learning new things and not being very concerned with the outcome. This is a big change from last June where I felt like I had to keep a rigorous pace of work it I was going to acquire any sort of "success".

Learning to "paint" and layer with Corel.

I remember one night when I was telling my husband that I couldn't veg out in front of the t.v. because I had too much work to do. His response to me was, "Man, that boss of yours is a real slave driver." I try to remember this when I start feeling like I'm not doing "enough". I'm making all these choices and no one is forcing me to work on my Etsy shop every waking hour. I think I have this deep-seeded idea that success will never come to me without sacrifice, pain, lack of sleep and exhaustion. "You gotta pay your dues", I hear.
I'm trying to let go of other people's definition of what success means and recognize the things that make me happy as my own measure.

I can say for sure that I will need longer than two months acquire this mind-shift but I'm optimistic about my progress so far. Do you have a sure fire way to lift yourself out of periods of self-doubt? I would love to hear your thoughts.
