You aren’t the most important person in the world to everyone.
Don’t be afraid to code badly. You can’t know it all from the beginning. And don’t let people get you down about that.
What can go wrong? How likely is it? What are the consequences? If it’s your business, you have to know.
Unless the wheel needs it, of course…
Be mindful in your use of add-on packages to your code. Only use what you need, and leave the rest out.
