Many people wish for their startup to be like a lawnmower thats already been started
I thoroughly disagree with this; getting everything set up just right is part of the fun of working for a startup.
The crapiness comes from the jobs you can't outsource. For me, things like staying on top of invoices and doing the petty little jobs that mean your cheap-as-chips accountant still does his job, these are the bits that I find difficult on a not-yet-profitable startup.
