We forget. We forget of lots of things, including how we actually learn and learn efficiently. Usually that is not a big deal as we have past experience or daily routine to remind me what had worked previously. However, those learned routine might not work continuously when the situation changes. If you cannot adjust it according to the “underlying principles”, life and everything begins to fall apart. This blog intends to introduce those underlying principles that are often omitted or forgotten as the life proceeds. Hope you can get something from it!
