This is what Steve Jobs had. This is what makes success.
The ability to remove every and anything from your mind, from your environment, to push all else off and focus on a single task, a single idea, a single product until it is complete.
To abstain from mindlessly browsing distractions, to not get caught up on the next big idea no matter how fantastic it is. To focus on the initial task until completion, until perfection.
This is something I haven't succeeded in. It is my goal.
If you can achieve this level of focus, you can complete anything at a level of detail higher than you've ever done and in a fraction of the time.
Practice focus. Start small, work up. Choose a goal. I'm about to work on a Critical Paper. I'm going to practice my focus on completely being devoured in this critical paper and shunting all other distractions until it is finished.
