Name: Chua Gek Huey (
Some of my thoughts and principles in life:

  • Others can let you down, but never let others down; 宁人负我 毋我负人
  • I advocate "Love what you do" instead of "Do what you love"
  • Event + Responses = Outcome; good outcome comes from good responses even if it is a bad event
  • Contribute back to society; 取诸社会 用诸社会
  • Success is when you make others succeed
  • Life is not meant to be fun, it is for you to make it fun
  • A little smile means so much; A little help means as much

Hobbies - spice up your life

Lifelong Learning
I call it lifelong learning, my friends call it cert/ license collection.
Some crazy things that I have done:
  • 3 master degrees
  • taxi vocational license, bus vocational license, bus attendant license
  • Ren dian xue
  • Numerology, Fengshui
What's next in the pipeline:
  • Master in Psychology
  • Hypnosis
  • TCM
I suppose when I retire, I can be a volunteer in counseling with studies in psychology and hypnosis and help heal or relieve symptoms of sick people with TCM and Ren dian xue.
I have to write programs or scripts almost daily. I put most of the things I learn into web based application so that there is low chance of totally losing the knowledge. Take a look in the 'Share' section of my homepage.
