If you’re going into social media with this mindset, you need to change immediately

For freelancers, social media isn’t about showing off what you can do and letting people know about all your accomplishments to boost your own sense of self worth. 

Instead, social media is a place for creators to show value and teach/entertain/perform/inspire their audience.

When you do the latter enough times, people will intentionally look for you to solve their problems.
