The recent foster parenting introductory seminar I was at spoon-fed us an answer that our local area wanted to hear on the question -
They wanted to hear that we like being parents/parenting
That we want to make a difference in society
That we "consider raising children one of the most important jobs in the world"
And that we "believe fostering will be personaly rewarding to my family because..."
I think that maybe one example from your life as to why you are interested (pick one, you have many!), and touching on the points above would be more than adequate.
ETA: Boy, I sound cold in the above. I should say that I totally get what you mean about not knowing what to say because you have so much to say about it. I am that way too. So I found it helpful that it was pared down and straightforward in that format. HTH.
I think it is good to start with the generic answers that "they" theoretically like to hear and then to end with a small bit of personal reason. For instance, in our homestudy, we gave the obvious "we want to help the vulnerable kids of our community, we love being parents, ect" first. Then we mentioned that one of my closest friends was raised by foster parents for 14 years of her childhood and want to help kids like her. Also that we have room in our hearts for more children. It was all honest truth of course, but I think if you tone down the extent of the personal reasons behind your desire to foster it helps you seem more "together" and "ideal". The truth is, Fostering is not easy on emotionally fragile parents so using overly emotional answers probably isn't wise.
Just my thoughts.
In all honesty, I would lose the "In my early 20's I struggled to find the right job, the right career but everything felt so empty and pointless (do I sound really depressed here?)." That makes you sound like you just figure you have nothing better to do than foster (which sadly, there ARE some people out there like that, actually.) I know you mean to say that you think you will be finally fulfilled by fostering (though again, in honesty, probably not something you want to put there, it sounds a little desparate on paper).
I would say something like "Now I have the resources and time available to finally give back to my community how I've always wanted to--through fostering" or something like that. Turn it into a positive, open, freely given contribution rather than "well, I thought everything else sucked, so here I am." Does that make sense?
