Steps
Work from home
Set up your business operations to allow you to work alone from home rather than forcing face-to-face interactions
Handle marketing solo
Write newsletters and do marketing activities alone where you can think and create without social pressure
Teach only when necessary
Go out to teach seminars or do presentations only when needed, making these focused events rather than constant social activities
Leverage your natural strengths
Use your introvert's ability to focus deeply and work independently as competitive advantages rather than trying to become extroverted
