Learning compounds like interest. A little now is worth a lot more than a lot later.

Everything you already know makes the next thing easier to attach, so early knowledge does not sit there, it multiplies what comes after. That is why starting now beats a bigger effort started later, even a much bigger one. The catch is that the early returns are invisible, so beginning feels like nothing is happening. Most people quit inside that gap.

Start the thing you keep deferring at a size you will not skip, fifteen minutes on a Tuesday. Do not scale it up yet. The point is getting the clock running, because the later you begin, the more you need to do for the same result.
