Are you comfortable pushing yourself outside of your fears? This is no easy task, but 'stepping out' will help you move yourself to the next level. This applies to all goals such as your fitness, your health, and your business endeavours. Following this advice is hard, but necessary if you are looking for personal growth. My suggestion would be to identify your fears and honestly determine where your comfort level is when looking at your personal growth.
Embrace new ideas and live adventurously!!
