Even though the company is just me, I approach it as a business and do a mix of hourly projects and fixed fee projects. At any given time I have 1-3 projects going on at once.
What I work on depends primarily on the client. With some clients it is all about the 'why' and we do real business analysis. These are massively rewarding.
Other clients treat me like someone who "Shovels poop for money" and just want me to do whatever they say. These are not as rewarding--but are often profitable.
