No matter what the starting point is or what the goal is, your effort toward accomplishing it is solely in your hands. This control of how hard I work, how much can I can focus, or how do I get more effect so I can get more done in the same time? The ability to continue to grind is what separates people who reach their goals and those of us who succumb to it not happening on our timeline.
Keep focused on the work and making progress over yesterday. Do a bit more. Get better at things. Keep learning.
