If you need quick motivation I recommend watching "Jiro Dreams of Sushi". You pretty much want to copy his mindset. The hard part is of course the "finding something you love to do" part but I'd argue all the subjects that are abundant will merge naturally. You "just" need to identify the driver. You need to find your Sushi stall so to speak. Once you find that (somehow related to CS) all the topics you mentioned will arrange themselves and you'll want to learn all of them to get better at what you love.

So basically pick a project and start it. Then ask yourself "will this make the output more excellent" for everything you learn.
