I learned four things:
- I should check my work more thoroughly/often.
- It is okay to accept help if you are not 100% sure about your ability to do something.
- Do not try to rush something just so you can leave as soon as possible
- It is not the end of the world to make mistakes
Next time I would accept the help in the first place. That would have been enough to have prevented this situation from happening. Luckily, my boss wasn’t angry and didn’t make a big deal out of it. Which is something I had feared before, but it has taught me that it is okay to make mistakes.
