I think it depends. For simple notes/reminders/to-do lists, paper and pen are enough. But for bigger projects, you might need a tool. Choosing the right tool for your needs can make a significant impact on your progress. That's why there are so many PM tools on the market. Cheers,

All tools are indistinguishable from a sufficiently advanced set of post it notes.
