Seasonal Themes Are the Best

Seasonal themes would make a perfect beginner's mode for theming your life. Arian asks, have you considered quarterly themes? Ie, every three months. Am, but i id i thought about it, but i'm not personally sold on how i would implement it. And lou asks is the yearly theme simply a way to categorize activities you would have undertaken regardless of the theme? Or do you actually find the theme driving new activities you wouldn't have done otherwise?
