I am a believer of the "early birds get the worms" theory .
It's best to start the work early, clear as much work as possible and get back home on time to spent time with family.

I am amazed by some peoples' working style .

Already late for work but can still go for breakfast. What's packed breakie?

People who don't make a point to be early for work, indulge in a lot of small talks and & does personal stuff at work. Then late in the evening , they will start their office work & "disturb" fellow colleagues who are abt to head home.

Damm...Be considerate.
