The Old Soldier is here to give you some tough love. The first thing you need to know is that 99.9% of all writers do not, I repeat, do not make a living writing. They have some other means of supporting themselves. (I have social security and two pensions.) Once you accept the implications of this fact, it becomes imperative that if you have to work you should find a job that you like, or at least can tolerate, and that will allow you to keep writing.
And one more thing. Writing is not a destination. It’s a journey. So enjoy the ride. And keep writing.
