Those are great advices @triptolemus. Indeed, trading your time for money is the worse trade you can ever make, as Tony Robbins says in his book Money: Master the Game - “money you can always get more, not time.”
By the way, I’d really recommend this book to anybody that wants to achieve financial freedom. It is loaded with good information and advices from the top traders. Above all else, it helps you build a plan to keep your financial freedom and not run of of money !
