Work related matters

Surprisingly, human at work in this century, living in the fast pace city always demand. Demanding non stop.

If you are in a service industry or an end user environment, your user, colleagues, line managers, supervisor or sometimes sub ordinate (very rare though) could demand things from you. Things that you have done before after a certain time. They could demand again. Just to fill their satisfaction.

And you know, one way of meeting this just to do whatever they ask, satisfy them, "just do it". Of course must always set a boundary as to where to stop.

Try it.
"Just Do It"

Three valuable Life Experiences

The other day I was reading "My paper' (http://mypaper.sg) and found the article published very interesting and very information and would like to share with you out there. I noticed that it fits into my life very well and if I have known it or whatsoever some of my bad experiences in life might be able to avoid.

1. Never take short cut/route
There's no easy way for life and money. Do not attempt to de tour that usually sounds tempting

2. Do not be curious with things that are bad
Never in your life try to be curious with things that are not bad. Do not attempt to try it as it will ruin your life

3. Always stay calm before you act
Do not act when you are highly unsteady with you mind/emotional

Back from Vietnam Trip

A nice trip back from Saigon, Vietnam. Spent 3 days 2 nights there.

It's a wonderful experience. Things are reasonable priced and cheap. You can get good bargains in the market.

Breakfast on Sunday was a chicken tuna sandwich in the airport.

Evening back to Spore. Wasn't feeling good. Got indigestion. Went to see doc. The relief doc was crappy.
