ចង់ប្តូរការងារ ឬ កំពុងស្វែងរកការងារ ផ្វើសារឥឡូវនេះ
If I am a doctor and I know how to work with only one patient at a time, there are just two ways for me to make more money. One is to work longer. The other is to raise my rates. But if I keep my job and work in my spare time to find a drug that cures cancer, then I will become rich by serving many more people.
