Quotations to live by:

• “At the end of the day, ship the f***ing thing! It’s great to rewrite your code and make it cleaner and by the third time it’ll actually be pretty. But that’s not the point—you’re not here to write code; you’re here to ship products.” – Jamie Zawinski
• “So, no, you shouldn’t reinvent the wheel. Unless you plan on learning more about wheels, that is.” – Jeff Atwood (and probably tons of others)
• “Build what you need as you need it, aggressively refactoring as you go along; don’t spend a lot of time planning for grandiose, unknown future scenarios. Good software can evolve into what it will ultimately become.” – Jeff Atwood
