like this one: teaching is an effective way to learn

This one is especially true on this forum. If you find time to correct others' English usages and pronunciations, you will actually learn more than you are doing on your own.

Just hope that all people here are receptive to suggestions and critics. Anyway, any cheer/awe you got here is absolute nothing since it won't help you increase your income, but the suggestions/critics are very valuable, which people can take them back to improve upon themselves.
