Pls help me revise the article,thanks.

I worked in a company in the past.I was busy with the work every day.Once I was putting some important information into the computer while my boss was talking with the other colleagues,suddenly the boss asked my thought about what they were discussing,I had to say sorry,for I didn’t hear what they said.Later my boss told me.that only use your eyes,mouth,ears and heart at work can you become a smart one.



Sometimes I think my boss is so strick,but what he said sounds reasonable.
