Do you never seem to have enough time?
I will admit that I tend to put off things I want to do for myself (hobbies, etc.) until after I have wiped all the other tasks off the board. The problem is, the board is never going to be empty as there's always something to do.
It is very important to allocate time for yourself, so instead of trying to finish everything on the board BEFORE you have "me time", put the "me time" on the board too and allocate time to do it.
It sounds simple, but then perhaps it is supposed to be!
