There’s no “right” way to design a space. Sure, there are basic design elements that we generally follow, but every person has unique preferences when it comes to design.
For instance, a space that makes me feel at peace might be uncomfortable for you; I may prefer cool colors, while others prefer warm; some like a minimalist design, and others like a lot of stuff in their space.
What's important is that your space meets your unique needs in both function and aesthetic.
Pay attention to the places you most enjoy being: restaurants, businesses, a friend's house... These places offer a helpful hint as you seek to discover your own design style.
