The threshold is the potential that a cell must reach when depolarizing in order for an action potential to occur. The threshold is also the point or value that I must obtain on my exams this week in order for me to pass and for my career in medicine to continue...
I feel like I am kind of standing on a threshold, the threshold of my life, and that this week will determine a lot (but not everything, because, as Amy suggested, I'm giving myself till Christmas).
I didn't expect to like my med school class this much this year. I didn't expect to enjoy it this much. I didn't expect to make this many friends. Last year I didn't really care. This year I do, for more reasons than just my future as a doctor.
But, like my fellow student said on the way to chapel a few weeks ago, there's not really any reason to worry or be anxious, because it won't accomplish anything. It will just make me miserable and make my studying less productive. So I'm just going to do my best to not worry, trust God, and do the best that I can on exams this week.
