They didn’t work for me.
At the start of every month I used to write a bunch of goals (well more like to-dos), maybe around 25. At the end of every month I never failed to have at least a few things left.
28-31 days is a long time to plan for and I found myself just sort of creating a random todo list of stuff for the month that I just never stuck to.
I’d write them with good intentions but my actions for the weeks that followed were somewhat half-hearted.
Now granted the solution may have been to just get more committed but I actually just switched to weekly todo lists instead.
I’ve found that making plans for myself every seven days gives me a chance to be a lot more focused.
And as a result I’m slowly but surely getting better at getting things done.
