Something clicked for me recently - you must never, ever stop improving yourself.
Since I left school I thought I would never have to study again. Actually, work forced me on a few occasions to study for exams and gain certifications. It never felt good, like I just was forced to do it.
I had long periods of no improvement at all.
So after reading this post, please set yourself some goals and start reading regularly, at least twice a week, some kind of development books, be it self improvement books or money or finance or books in your career, even history I am starting to read a lot lately.
Also podcasts are great to listen to and find out more in your subject!
Hope this post helped you :)
