Choose only a job that will give you a substantial annuity or pension upon your retirement. Otherwise you will forever be constrained to work through your dying day and perhaps even pretend that that is how you want it, constantly prove your worth, continually check your marketability, remain in the headlines to maintain your popularity, push your PR skills across the borders of hypocrisy, and take vacations not when you want to but only when you are able to.

You will also be compelled to keep updating your curriculum vitae--something I stopped doing in 2015, when I retired.

Worse, you will always be a slave to time and to other people who will be most delighted to have control over you.
