Do you guys set goals for yourself to upgrade to a "next" bike?

For me the immediate goal is no new bike for 2 years! And I don't see myself owning more than 2 bikes.

The other criteria I have for myself are:
-Once I'm able to ride one of the routes around my house at 20mph... (right now my personal best after 3 months of riding is 17.0mph)
-Once I log 10,000 miles
-Price of final bike will be in the $3000--and will most likely be a FELT or ORBEA

Do you guys ever plan out your purchases or set goals for your next bike so that you keep your eyes on the prize?
