Did you get your last month's salary? If you get it, that's fine. You can fend for yourself. Are you a programmer? Is it right? ok, last month's pay just puts you ahead of 80% of the wage earners in the world, not to mention those who can't find a job. So if you're still getting paid next month, you're not an impostor.
