5. It's a common misconception that if you do something you love, it won't feel like work. Of course, there can be huge challenges, the tax return is never enjoyable, and sometimes the lure of a duvet day is overwhelming. So love your start-up business with everything that you've got. Start every day fresh, be optimistic, and never stop learning. Much like a child, you need to take care of your business until it's strong enough to take care of you.
