There are two main fears in our lives and these are an obstacle in getting what we want. The two fears are:
1. Fear of failure
2. Fear of criticism
At the end of the day, failure is part of the journey on the way to success and criticism is a sign that you are doing something that some people are not comfortable. That's life. These people may be your friends or family or they could be complete strangers. They are just not comfortable with it. That's their problem, not yours.
My friend has been developing his consultancy business over the last few years and we have always joked that when we find his name plus the word scam after it then he has kind of made it, which is so true.
If you find that you are not getting any criticism then you are probably not reaching enough people and that is not good. You should treat criticism as feedback. You don't necessarily have to do anything about it because the critics might not know what they are talking about but you should embrace it as a good thing.
I know as an introvert, failure and criticism can be almost as bad as death as we tend to take things personally but remember that you are doing something positive with your life. You are creating something that could be influential in other people's lives. These trolls have nothing better to do than bring you down because either they don't have a creative bone in their body or they are so bored that just looking for something to amuse themselves. It's probably both.
Remember, failure and criticism are two parts of life that you can't escape from. Embrace them, embrace them for what they are keep going on your purpose and your vision and think the more you are getting criticised the better things are going.
