Hi there Mom :-)
Here`s one topic you might take a look at:
"What kind of business can someone start
Here are two about passion, both of which are good food for thought:
"Pursue the Passion
"Finding one`s passion
Another fun topic was how to start a business with $200
What it comes down to is that if there`s a will, there`s usually a way.
:-) Notice in your own post you state what you don`t know or aren`t
sure of. A better way is to forget about the "how" for the moment, and
let your imagination roam free.
For example, "I`d like to have an online community for moms like me. It
would be all about this topic and that topic, and give moms and maybe
dads a place where they could talk. I want it to include this feature
and this other one, and I can see it being really useful this way and
this other way."
See, it`s more about developing your vision of what you want. It`s not
so much about starting with each piece of a vision then trying to prove
that it will or won`t work. :-)
