would you be more open....

So I have been on this subreddit for a while and one thing I have noticed are people are very coy about the financial aspect or self publishing. They never give specifics how much much they spend and take home. Which is cool but it got me thinking if you published anonymously would you be more open about financials (writing only)?

​

the reason I ask this is because I would like to replace my job with writing one day, and we need money to live, unfortunately.

I am not asking you to give me specifics in this post (only if you want to) just asking what stops you from talking about money.
