But keep in mind: whatever you might want to change it must be in harmony with your mind, body and soul. Do not just decide to work more if you do not have time to go to the gym/massage/vacation or you do not have time to reflect/meditate/self develop.
"Writing is not like dancing or modeling; it’s not something where – if you missed it by age 19 – you’re finished. It’s never too late. Your writing will only get better as you get older and wiser. If you write something beautiful and important, and the right person somehow discovers it, they will clear room for you on the bookshelves of the world – at any age. At least try." Elizabeth Gilbert
