The Most Powerful Tool For Productivity
It's not a mobile app.
It's not software on your desktop or on the web.
It's definitely not a system, no matter how simple or how arcane.
Your skills. Your discipline. Your focus.
Tools are useful, but they're not the be-all, end-all. Tools only exist to help remind you and to help keep you on track. They don't help you push beyond procrastination. They don't help make planning and sane task management a habit. They definitely don't do the work for you.
It's all up to you.
If you truly want to become organized, if you truly want to become productive then fight that urge to check out every new tool or technique or system under sun. Use what works for you.
It doesn't matter if what you're doing seems old fashioned. It doesn't matter if you're not using the latest and greatest app, the one everyone seems to be raving about. It doesn't matter if you're not doing as much as the next person. What matters is doing what's right for you, using what works for you, and whether or not you're finishing what you need to get done.
In the end, that's what productivity is all about.
