Whenever you try something new, you are uncomfortable. However, after you have done something a few times, the fear disappears.
Usually, the first time is the most nerve-racking.
This applies to public speaking, technology, meeting your in-laws or your potential biggest client.
Doing some preliminary preparation and taking the first plunge is the foundation of eliminating or reducing your fear.
Next time you are faced with fear and a nerve-racking feeling, take a deep breath, prepare well and take the plunge. You will be pleasantly surprised!
