Your questions are answered in the thread, which is a pretty significant feat to overcome (I ditto the pomodoro method, exercise, and higher expectations). That said, laziness is not all bad. Keep some of it in case you need it. Given sufficient motivation, I recommend aligning your productivity with meaningful outcomes. If you can't, you will be back here looking for another solution in not much time with a bigger problem. But then again, there are worse things in life than being lazy.
