I've been using Beeminder for 8 years[1], and it is no exaggeration to say it has massively changed my life. It helped me run a marathon, procrastinate less, write more words, workout regularly, and a bunch of other stuff.
It's weird and it's not for everyone, but if it works for you then go for it. I'm not ashamed that I need to wear corrective lenses, and I'm not ashamed that I needed help to get my shit together.
