Ideas coming to me

I have this peculiar way of having ideas when I least expect it, especially ideas on what to blog or some other money making ideas.

I am not sure about you, but my ideas usually come when I am driving (and therefore have no hands to write them down) or when I am bathing (and therefore would have to expose myself if I decide to grab a pen) or when I am about to sleep (and therefore would mean I have to get up, find my pen and paper in half darkness and then finding myself wide awake after writing them down).

So, when I finally do sit down like this to write, my mind is blank and hence I am writing this. I actually did have a brilliant idea just now while I was bathing ... now I cannot remember it.

Don't you just hate it? What about you? When do your ideas usually come?
