Write an awesome bio! Your bio section is a 160 CV of your amazing self. It can be funny or serious, but make it clear what you do. Use hashtags to identify your interests or handles to identify people you post with.
Focus on your passion! Stick to tweeting about what you know best as people will go to you as an influencers in that industry.
