Use your mind, analyze the situation. Look at what you'll need to solve the situation and what your weaknesses in this task are.
Then seek help from a specialist and follow their advice. In the end, it's you who has to make the steps.
When the card of The Hierophant is drawn, then there is something you want to achieve or solve. You'll be able to do this, because it's not the first problem in your path.
Go it alone, don't seek help. You can make it on your own. Don't bother others with your problems.
