As someone who is rather shy when it comes to talking to strangers, asking for help can be quite an unpleasant experience. Often, I choose to just skip asking for help and attempt to solve whatever issue I have by myself. In trying to not look stupid, I did probably the most stupid thing you can ever do when you need help. Not asking for it. Think of the time and effort I could have saved if I opened my mouth and ask.

Most people are willing to offer their knowledge and expertise if you ask nicely. We inherently love to share things with others. Those that don't are often shunned and avoided. It's okay if someone refuse to help you. You just need to ask someone else.

The most important about getting help from others is that you get to learn from their experience. There's no reason to make the same mistake by yourself to learn from it. You can learn by asking too.

You want to learn from experience, but you want to learn from other people’s experience when you can. - Warren Buffet

Obviously, you can't rely on others all the time. At the end of the day, you still have to do the hard part yourself. But it can make things easier and it doesn't hurt to ask. Just remember to show your gratitude and offer help to those who need them.
