Hire people who are smarter than you are.
Part of building a successful business is knowing what you do best (and enjoy doing), and hire people to do the task you hate doing or you aren’t good at. I code very well, but I don’t enjoy doing it, so I have a technical co-founder who enjoys coding for long hours every day.
All good entrepreneurs aren’t ashamed to admit that they don’t know everything, and hire people whose strengths complement their weaknesses.
If you hire people who bring to your business skills and knowledge you don’t have, then you’ll have teammates you can rely on when things get tricky.
Also, this gives you a lot of learning opportunities as you observe them accomplish difficult tasks brilliantly. If you don’t understand things, ask. Don’t be ashamed to admit that you’re not always the smartest person in the room.
