Here are some of the reasons that some people change jobs every 5 years +/- a few years:

1. Discovery. A new job provides opportunity to learn a new industry, skill or even perspective. You are finding and developing your areas of interest by tackling the unknown.
2. Good things come from putting yourself out there. Opening yourself up to a range of individuals and networks has a huge professional advantage.
3. It teaches you how to take a calculated risk.
4. It pays. Career advancement and more money.
5. No one will judge you.
6. It’s a reflection of the new workplace reality. The whole workforce in this country is becoming a flexible workforce.
7. The Peter Principle. The Peter Principle suggests that many organizations promote their employees to positions that they are not actually capable of doing – and that’s where they stay. 
8. Your reputation. To develop a broad range of experience. 
9.  Survival. A broad skill-set reduces your chances of being caught in an obsolete or shrinking field, and provides a life raft.
10. Firm Policy / Necessity. Some firms have a built-in culture of turnover. For example, it is well known that large accounting firms hire a lot of young people to do their auditing and expect at least half of them to move on.
