I plan to start my Comfort Zone Crusher course some time this year.
Here’s a few good citations about beliefs that hamper your social life:

You don’t need to make people like you. Learn to be okay with who you are, and you’re going to attract people who naturally like you.

The easier you are on yourself, the more likely you will say something that resonates with the people around you.

Your social skills are good enough. Instead, work on overcoming your fear.

Fear is NOT the problem. Our reaction to fear is. Instead of learning to get rid of fear, we need to learn to take action DESPITE feeling fear. This means saying “Hi” to a stranger, even though you have shaky knees, trembling hands, and a squeaky voice. Take action despite feeling fear. This is what courage is all about.
