So I’ve been working on a DIY pottery wheel for my daughter and my brain is firmly in obsession stage.

As far as I can tell, here are my mental stages of a project like this:

• Mild interest
• Research
• Initial purchases
• Frustration
• Dawning comprehension
• Obsession
• Exhaustion
• Breather
• Second wind
• Completion

The last two steps are optional.
