once i have been published, then what?

[Gary]

i am writing a series of story telling songs that i plan on turning into childrens books..
a relative of mine said that he would publish my first book..
but then what?
how does the book get known?
at some point i want to include all the story's into an anthology with chapters discussing the behind the scenes story..
i am sure that this anthology with the background would allow me to be a guest on Coast To Coast AM late night talk show..
is that a better way to go than shooting for kids books?
i somehow would like to do both..
but as someone on disability i don't want to start selling childrens books and lose my disability and then not get very much money from the books..
any advice or info on this would be appreciated..
thanks you~
it's not that i want to make money..
i just want to be stable..
disability isn't a lot of money..
but i am worried that writing books i might make less..
i don't know what resources my relative has to offer me..
but if it is minor then how do i make up the slack?
bob?
