how to start my own business??

I want so desperately to have my
Own business! I want to start it but have no clue as to how to get it started. I currently am a nurse but my passion is design, fashion, and crafting! I was wondering if anyone out there knows how to make this dream
A reality?!? I want my office/craft room like the pic and if you haven't noticed I'm loving pink! Xo~A
