Start somehow, remember it's a job, not a marriage. Stay aware of opportunities, beware of committing the resources of others, you are ethically responsible. Don't screw folks on the way, you need to keep all possibilities open. Know the law, err on the side of ethical behavior, legal but unethical is inexcusable and ultimately self-destructive.
Spend as little as possible on yourself, save what you don't fold back into the enterprize.
Keep your eyes on the prize.
