Manage your time as a bedroom programmer. Pick projects, contract-work and vacation days to get by, then start to build some passive income through your startup.
Beware though: Once you start hiring your first employees and upgrading your office, you'll attract the attention of competing businesses...
Don't Panic!

   You decide how each project goes and what to focus on
   Spend a week training your staff, or earning money, or building features... but choose wisely!
   Upgrade your company in the skill tree: Will you take longer vacations or cheaper air-co?
   Hunt for new employees and hire the ones that fit your style: Social butterfly? Marketing expert? Lone Wolf?
   Compete with rival CEOs for new users in your region, and then expand out by building new headquarters on a world map!
   Hurting for cash? You can take out a loan or search for investors, but don't think it'll come for free...
