I hear this a lot, and I’m here to tell you: No you don’t (maybe!)
The first thing you need to do is ask, why do I want Twitter or why do I want social media in general? What’s the ROI you’re looking for? If you have a visual brand, I’m looking at you beauty/fashion/interior design, then Twitter might not be the right fit and I would suggest focusing your efforts on a visual platform like Instagram and Pinterest.
Twitter is great for writers, networking, customer service, and and people who want to share their expertise.
The second element you want to consider is, do you have enough time for Twitter? Assuming you have a whole other business you need to run, you may not have time to dedicate to building your Twitter account in a meaningful way.
Maybe you’re feeling confused now and unsure which social media platform(s) to focus on to promote your business. I can help!
