If you are working on something you have never done before and this is unfamiliar territory, reach out to 2-3 people who know about this subject than you do, and ask them questions. It might be hard to call them out of the blue and ask, so just ask for 10 minutes of their time. Their advice will motivate and inspire you, and give you the confidence to proceed.

Pro tip: surround yourself with people who won't judge you, and put them on speed dial. Let your friend do the same. This will help you get unstuck many times in the future.
