Being a creative, as an entrepreneur, as a person starting a new education or career. You might be working outside the normal evaluation system and the norm of your social group. When you create or do something new, most people can’t evaluate it based on anything they know, and it confuses them. The majority will react against what you do, to get their worldview back to status quo and feel validated in their own choices in life.
The build-up stage of a business is super lonely for an entrepreneur because you must rely on yourself. I can tell you that when you break through, the loneliness can hit you again, because you grew so much as a person, that you are not the same and will feel detached from some friends and things you used to feel familiar with.
For you to succeed you must push through the fear of standing alone. You must be able to rely on your gut feeling and stop seeking advice among people who have no idea about what it is you are doing.
