I have tried a number of Project Management Systems over the years. If you are like me, I manage many projects at once (exhibitions, schedules, inventories, curatorial, etc). Most of us who live a complex life need a digital assistant. My favorite one is NOZBE. You can find it at www.nozbe.com. In my projects, I have categories for just about anything I need. I can also link to Dropbox and add notes any time.
The best part of it is that it synchronizes with your iPhone or Android smart phones and it is accessible from the web. So no matter where you are, you have access to your projects. If you happen to loss signal in your device, no problem. The data is stored in your mobile and synchronized when you need it. Besides the web based access, you can also download an app for Mac or Windows computers. It’s that simple.
Artists could benefit from having an organized Project Management System to keep them on task. Make projects for your exhibitions, add deadlines, submissions, price inventories, etc.

Sounds very appealing. I am always struggling finding the perfect solution for me, and find myself switching the software ever so often. Currently i am using evernote, but i always keep my eye open for something “better”. I am wondering, how much does nozbe cost?
It costs 89.95 per year or 9.95 per month. You should try it for free first before you buy it.
Thank you for the information and recommendation.
I would recommend checking out http://www.Gtdagenda.com for an online GTD manager.
You can use it to manage your goals, projects and tasks, set next actions and contexts, use checklists, and a calendar.
Syncs with Evernote, and also comes with mobile-web version, and Android and iPhone apps.
