Lots of high paying and low paying jobs permit this. Even airline pilot—- 75 hours per month guaranteed of flight time and up to 100 hours per month allowed via “overtime” (25 hours of overtime at a very nice multiple x hourly pay rate bump) per the FAA maximums. Lawyers bill by the hour. Flight instructors, charter pilots, academic tutors, construction workers, consultants, and generally most independent contractor work.
If your field of work is high paying and in demand hourly pay and creating your own schedule is the way to go as you don’t need all those “assurances” of a salaried job as your skillset isn’t easily replaceable and your skill set is in high demand. In this scenario work will always be there for you so to speak and your most valuable asset is your time and that is something you cannot buy more of for the most part however many Silicon Valley executives actually try to do so.
Sometimes the salaried assurances are worth it sometimes they are not. My advice is acquire an “exclusive” and “hard or expensive to replace/acquire skillset” and then work on your terms as the work will always be there when you want and need it….. An investment upfront for an increased quality of life on the back end.
Best jobs for this are: 1) IT, software developement, cyber security basically any thing computer and technology related. 2) Medical doctor and medical scientist. 3) High demand trade skills: i.e. Airline pilot, fork lift operator, electrician, plumber, aircraft mechanic etc. 4) Entrepreneurship: find a big problem and find a way to fix it on a mass scale with your own ingenuity and angel investors.
Best advice I’ve received: “time is your most valuable resource spend it doing the things you love and surrounded by the ones you love whenever possible.”
