Quote from : Endless Encores: Repeating Success Through People, Products, and Profits Book

If you don’t own the company, it’s their job, not yours. They lease it to you for a while for the value you create beyond what you cost. At the end of the lease, if you paid off the tab and have more valuable knowledge and skills than you had when you signed on, it’s a good deal for everyone. If you take their money but don’t get better at what you do, you got burned.
