My advice would be do something seriously FUN as a first project. Do you have a hobby that could be a springboard? For example, I love Radio-Controlled stuff. So a project could be arduino controlled R/C car/drone. A little coding and a little wiring with real results. It's not trivial, but it's not over the top difficult either. That's my example, but try to get a concrete project to tackle. You will learn what you need to learn in the journey to finish it.
