The question of what to do (or what to do next) seem to freeze us. The possibility of a wrong choice instills a level of fear not rivaled while in motion.
The truth as I know it right now is that there is no right answer. All I can say is to explore what interests you. Examine it. Play with the idea. What about the idea gets you excited to talk about it? Follow it like little bread crumbs in the woods. Find your rabbit hole and jump in.
The next "thing" is often hidden from where you currently stand. As you move around, you might just be able to get a glimpse of it.
