It sounded like you supported what the original commenter said, not to worry about investors.

Having a slack attitude towards money (our own money or others) doesn't build a business or an understanding of value that ultimately ends in a revenue stream.

It's nice of you to share you story -- I don't think many folks do. I have similar experiences (good and bad), but I think the one thing that really stands out for me is that investors are in a sense "buying" your time, not much different than consulting...... :)
