Working from home

I am just thinking about innovative ideas to start a home business. I must say it is pretty challenging and I am so cross with myself for not having come up with an idea. I want to start my own business and I am mentally tired of coming up with ideas and dismissing them for lack of generating any income. I am doing lots of research, reading etc. I guess that once one becomes a mum, priorities change and adjustments have to be made. I can't begin to think of leaving my little angel in a day care now. But while I am at home I feel I need to be doing something to generate income. What to do???
