1. No one knows what will work. Try, see, then keep on iterating until it works.

2. Most companies are overstaffed, and most companies are overstaffed with the wrong people.

3. A product that does not serve its audience will eventually die. Listen to your customers, let them guide you.

4. Your customers will pardon your mistakes if they see you're working hard.

5. No remote work.

And that's just off the top of my head.
