Great topic, Ben. I'm surprised to not see about 10 pages to this topic already!
I had a goal, for 2017, to move onto another situation. Don't get me wrong, my current job is OK, but it lacks challenge and other things. Getting a new position didn't pan out. So 2018 I've decided to try and start a small software development business on the side. Something I can do a few evenings each week and on the weekends. I've been challenged to come up with goal as to what sort of software I'll work on. Towards that end, I'd welcome any input I can get from people here.
