Ask a friend who you think might be able to help. After all, what are friends for?
Ask a mentor.
Find a mentor. A mentor doesn't have to be someone that you pay. You can passively be mentored by someone. Find someone who has achieved what you want to achieve and follow them on social media.
Hire a coach. Do your research.
Google it. Have a "BS Detector" here helps tremendously. Be careful where you get your info.
Set a deadline. Sit on your problem and think it through, but set a deadline of taking action so that it doesn't eat away you for months or even years.
Find a group of like-minded individuals. Facebook groups, Meetup, Reddit threads, and I'm sure there are plenty of other communities online and in-person that you can find that will help you.
YouTube it. I'm blown away by how many videos are on YouTube that show you how to do things like home renovations, workout, and cook. Again, do your best to use your "BS Detector" and if you're struggling, then share what you find with someone within your network that knows more about the subject so they can verify if what you found is legit.
Nothing. One of two things will happen here. Either the pain of not taking action will continue to eat away at you for a long period of time OR the pain will get so great that it breaks your pain threshold and you decide to take action.
Just do it. There's no better learning than doing, failing, and adjusting as you go. Weigh your own risk tolerance with this strategy. If the stakes are too high, then figure out to make them lower so that you can semi-confidently take the first step.
