While I have co-founded, built and sold two multi-million dollar technology service firms, I admit they were never truly profitable. Every increase in revenue seemed to be matched with an even greater increase in expenses. Every day I checked (and still do) my bank balances. As the balances would climb and fall, so would my confidence and my spending. I lavishly incurred new, unnecessary expenses when my bank account was fat. I panicked when it was thin.
