If you’re stuck, if you’re struggling to solve a problem (be it a software, product, or people problem), ask for help.
Being proud and stubborn will not get you far. On the other hand, humbleness can save you and your entire team a lot of time and frustration.
When you don’t know something, when you can’t handle something, find a person who can and ask for assistance.
Not only will you solve your problem faster, but in the process, you’ll acquire important insight that you’re most likely missing.
