With the current world conditions forcing us to stay longer indoors, you've likely tried to pick up a new skill. If you aren't an active learner, you may think it's taking you too long to pick up that new skill. But slow learning often has more to do with our ability to focus and our attitude towards learning than our innate (天生的）ability to learn. Let's take a look at three reasons why you may be learning slowly.
Lack of focus makes learning slow. But once you improve your focus, you'll be surprised by how much faster you can gain new knowledge and skills. So try every means to improve your focus. Choose a quiet environment to do your learning and ensure you won't be interrupted.
Unrealistic expectations make us believe we're slow learners. Whenever we want to pick up a new skill, we assume that the learning process will go smoothly. When we don't meet our unrealistic expectations of how fast we should be learning, we think we don't have any talent or that we aren't smart. So we must keep our expectations realistic.
The person who's already a good surfer and skater has a foundation of board sports to transfer into snowboard, which will make him learn the new skill faster. We may think we're slow learners when we compare ourselves to others, but they may already have knowledge and skills that allow them to pick up the new learning much quicker. The more we learn, the faster we can learn new things.
A. Beliefs have a strong influence on learning.
B. You might even think that you're slow learner.
C. We don't know what they've learned in the past.
D. For instance, remove as many distractions(分心的事物) as possible.
E. Previous learning affects how quickly we learn something new.
F. The strategy here to become a faster learner is to never stop learning.
G. But the reality is that learning is sometimes frustrating, stressful, and slow.
