I recently have created custom typography for Geneva from A Pair & A Spare's series of posts on doing what you love. Especially for me, being a student, casual merchandiser, blogger and graphic designer / typographer this series couldn't have come at a more perfect time. Multi-tasking to the extreme is something I have become very familiar with lately normally resulting in minimal sleep and a whole lot of stress.
I would definitely recommend reading this series, even if for a bit of motivation.
The first post on Getting Started is now up at A Pair & A Spare
