Quotations from Mister Matthews-1 (馬語錄-1)

#1
Life is short

Use your time well

Don't memorize everything!

Remember:

Important words are common,

and

common words are important,

so

only learn important words.

A learner's dictionary is a very useful tool for learning English vocabulary.
The Macmillan Essential Dictionary uses stars to show you the most common, most important words. Three star words are most common (highest frequency). Learn these words first, then learn two-star and one-star words.
