So, let's think of how you draw a line, step by step. First, you lower your hand to the page, and start ghosting between your points. Then, when you're ready to commit, you repeat that motion, this time with the pen touching the page - but there's one more difference between this attempt, and the previous one: you double check whether your pen is aligned to the starting point. That's not super important when you ghost, because what you're interested in is the overall motion, but when you ink the line, you want to make sure that you're not starting from god-knows-where, but rather the start point itself. And, the goal, is to find the perfect amount of time, where this gains you the needed accuracy, but doesn't sacrifice any of your confidence. Spend too little time there, and your line won't start anywhere near it. But spend too much - and this is the camp I suspect you fall into - and the muscle memory you've built up through the previous step (the ghosting step) will be lost. A good way to tell if this is happening (it's why I suspected that it was, because I noticed some instances of it), is if your line starts off a little wobbly, but then stabilizes as you draw. I hope this makes sense.
