can't learn english all day, need to earn bread/butter first

There are many other life skills far more important than language as white collar works to earn bread/butter for the family. Improving spoken English is just a second string requirement for living in USA. With all kinds of accent souding around us, it is much less urgent to improve our own as long as we can communicate with other coworkers.

I am practicing oral english for fun since I am sured that I gained all other necessary skills to survive in US.
