If you don’t have regrets, you’re not growing.
How can you possibly look back at your life at not think, “Mmm, I wish I’d done that differently.”
No one is born all-knowing. We all make mistakes. We all do stupid things.
If you can’t look back at your life and cringe and think “damn, I shouldn’t have done that”, then you’re not learning, you’re not changing, you’re not growing.
If you’re not growing you can’t be an entrepreneur.
