You don’t need to know everything in order to be a success and in order to have a phenomenal practice, but you must be willing to go after knowledge by finding those resources and those people who know the answers.
The biggest problem you will face is not finding out who can help, but getting past your own fears so that you can ask for the help you need to solve your challenges and get back on track.
Always remember, there are others in your professional community that were once in the same position you find yourself in today. Some of these professionals (the askers and knowledge seekers) are now successful way beyond their expectations. These people should serve as your mentors.
Learn to reach out. Learn to ask questions. Learn to obtain appropriate help and advice. You will be glad you did.
