The Importance of Learning
Learning enables people to have new understandings and new ideas about things. Learning enables people to master new means and new methods to solve problems. Learning enables people to break out of their existing problems. The small world of interests has moved towards the big world of openness and harmony. You must have a minimum learning ability, which includes the ability to engage in extensive research, the ability to internalize and reconstruct knowledge reserves, the ability to collect and process information, etc.
You must persevere in learning. You must live and learn until you are old. You must be good at learning from other people's ideas and learning from others. Learning is a process, and you can realize your own value if you persevere.
