I&#x27;ve been a GTD geek for a few years now and was a borderline religious user of Omnifocus. Its issue comes when you want to move from managing your task to collaborating on shared projects. Unfortunately, contexts just don&#x27;t cut it when other team members or stakeholders can&#x27;t see their tasks in the system because it put the onus on you to chase and keep your system in sync with other GTD&#x2F;project tools.<p>I grudgingly switched to Asana a few months ago and haven&#x27;t looked back. It supports a GTD workflow with the addition of excellent communication and integration with other tools. For example, I automate task creation with Zapier to follow-up on calendar events in my diary, follow up website leads, scanned biz cards, etc. Placing tasks in multiple projects is also super useful. Omnifocus still has a better mobile app UX, and I wish it would offline sync to make better use of precious planning time on my commute.<p>The part of this post that I already found useful in the few hours since I read it is adopting the Pomodoro time management technique. I found a neat OS X app that called PomoDone (<a href="http:&#x2F;&#x2F;pomodoneapp.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;pomodoneapp.com&#x2F;</a>) that syncs with Asana and many more task managers to keep focus in 25 min intervals followed by 5 min breaks. Thanks!
