As I recommend in the tutorial video above, my advice is to just set your homepage to be where your blog posts display (for now) as you're just starting your blog.
You have the option of setting your homepage to be a static designed blog page (customized) that can serve to capture email sign ups, sell a product, or otherwise in the future. But for now, stick with just a list of your recent blog posts as you still navigate the process of learning how to blog.
If you're setting your homepage to be the blog, then one thing you can consider is changing the settings to show the complete text of your blog posts right on the homepage, rather than a list that has short previews of each post.
Since you won't have many posts on your new WordPress blog for the next few days or weeks, this'll make it look like there's more content in the short-term, and you can change the settings back to a list and preview format once you've gotten your first 5 or so posts published.
To change these settings, just go to Settings > Reading.
