When self publishing you are free to do whatever you please you design your own book, and write however you want to write in your book. self publishing is something you want to do if you are distributing your book between friends, family or a smaller group of people or if you just want something on your own shelf at home. only some sites offer more (which I will list below) when getting an agent, it can be real hard some will reject you or even all until finding the one. its like your the feather in the needle stack not knowing when or who is going to see if your worth the time. but, do not get discourage ambition and determination will get you far a lot of famous authors, models, actors, got rejected a thousand times before one person believed in their talents.
I wanted to self publish at first not knowing the details behind self publishing some sites helped me determined that it is not the route for me I want to be world known. remember to send your manuscript to an agent of your particular genre they will either love your work or feel that your work is not right for them; do not take it personal.
