Don’t do too much
Multi-tasking and information overload are the enemies of effective learning. The human brain is an amazing organ, but it can only do so much at once. If you want to be successful in your learning efforts, you will have to set priorities. This is a key part of the goal-setting already mentioned above. Determine which learning goals are most important to you now, set aside other goals for later, and eliminate things that really aren’t all that important to you.
不要过激
如果想高效地学习，千万不要再同时做好几件事，那样不利于高效地学习。
