How do I tell my husband?

So I am currently the "bread winner" in my marriage and that is okay with me but at this point I really want to be a housewife. I want him to go and work 8-10 hour shifts while I handle home business and we don't have any kids but I would love to have one. How do I tell him that he needs to find a better job so I can quit mine after the February. Is this is considerate? How do I go about telling him this without sounding self-ish...
