If I'm fiddling with the terminal or the font, I know it's because I'm procrastinating. I've trained myself to quickly recognize such side-quests and feel a quick punch of hormonal urgency, which helps me get back to work (with mintty and Consolas). You don't need the bells and whistles.
For example, I recently reduced my terminal startup time to 1/3 what it was by putting in some optimizations. I'll be able to benefit from that for basically forever.
