Suffering with too many WIP never-ending projects? Here is what 37signals recommend:
— You need to focus on finishing WIP projects first. You can’t add new stuff unless the previous stuff is finished.
— Being 90% done could mean that you're still only halfway through the project.
— Don't work on two things at once. It's a huge mental burden.
— You need to focus on hard issues first and don't start with easy ones and wait until the end for the hard ones.
— Giving lots of time to a project is a curse, not a blessing.
