Agreed! I spend a kind of embarrassing amount of time figuring out how to adjust my goals and rates. One thing that has helped me is to (mostly) stick to a rule that I can’t increase more than one goal rate per week, and if I’m making a significant increase I need to also decrease a goal somewhere. Which is very helpful with figuring out priorities! (i.e. what am I willing to do less of in order to do more of this?)
And using the Beeminder calendar from this thread was helpful. I actually ended up getting overwhelmed with having all my goals on my calendar, so I started using IFTTT to add an event to my calendar when specific goals whose deadlines are most important are approaching, and that has worked really well for me.
