From my experience, if any high paying jobs will require you to spend substantial amount of time and effort in what you do. Especially in making decisions and taking risk which contributes to the business side. It's always nice to earn huge salary but the higher the salary goes, the higher the responsibilities are.

As fresh graduates, the common type of motivation to work is more of getting more digits in the paycheck. However, as time goes, people will realize that working is not everything about money. If you have a high paying job but you do not like what you do, you will not last long in the job. There must be a balance between work and life.

Certain type of industries pays a lot because of the risks at work and the requirement of being away from home for extended period of time. For eg., Airlines, Offshore Oil & Gas, Telco, etc. I don't deny that fresh graduates will enjoy the traveling, not to mention about the extra side income you can make from traveling. But as days go by, we will tend to get lonely especially if we are always abroad / away from home. Especially for those married people.
