If you have a good sounding name that can reflect your business, you have good reason to use the name, especially when you are going to remain the main person in the business (rather than a team or larger organization).
My own name is a horrible brand name so I went for something to reflect the purpose of my designs.
I was especially looking to imbue character, soul, into product design so named the business Designsoul.
It also works as an umbrella term for smaller labels or initiatives - Designspark, Designsole (shoes), Designscribble (blog), Designsponge, Designsoup etc.
I am looking for a new name though to reflect something more concrete, more powerful and less lofty sounding, something in the line of
Pulse
Amp
Spark
