Productivity is personal. Everyone has their own style and pace. That’s why productivity hacks are just tips. One person may succeed off a checklist approach; another person may need a visual cue. Some people need both.
The new age of workers prefer digital tools. A digital to-do list in a spreadsheet, an app like Wunderlist, or in Evernote helps them keep track. Some people are old-school and need write everything down other-wise the list of things doesn’t stick. Some people toggle between analog and digital. I personally dump all my to-dos in Evernote and write down the priorities on pen and paper.
It comes down to personal style. If the new app helps, use it. If voice memos work, use them. If the putting your task list in Moleskine versus regular paper helps inspire action, do it. If your job circles around putting out fires then you may not need a priority list at all. At the end of the day, productive habits are only as efficient as they are in helping you focus and get stuff done.
