Has anyone here ever felt like time is running out? I don't mean in a deathly way, or in a sense of "time flies".

What I mean is, like when you are going to begin a task, such as learning to code in PHP for example. And I begin to start reading, applying and learning, but I get this inner sense of running out of time. I get this frustration that by learning PHP, I won't have any chance at all to ever learn C++.

It sounds insane, but that's the best way I can think of to describe the inner feeling. It feels more like, a subconscious feeling than something I would actually consciously THINK ABOUT.

Maybe it is my mind trying to secretly procrastinate, by trying to get me to stop the task at hand?
