Thanks for your message and your interest!
Yes i work as designer also.
Basically i develop what games i like. I like the simple but addictive games.
I start with a good idea and try to focus to this until finish it. In the meantime if i have a new idea, remain safe in a text or paper or whatever.
From my experience if you pause something and start with something else, at the end will have a lot half projects. I wish you all the best!
