What focus means?

During the whole of December, I tried to follow one approach. It bases on focusing on one specific action for a week. In theory, it should allow concentrating on one particular task. And you have to complete this task before starting something new. It is substantial to keep focus to do not lose track, especially if you generate ideas every day, like me. Or, you have limited time for your projects and need results.

Some time ago, I watched a pretty old interview with Jonny Ive about Steve Jobs. In the video, he spoke about one interesting peculiarity of Steve. He was able to be strictly focused on what needed to be done. Here is that video. Please, watch too.

What focus means? It's saying NO to something that you think is a phenomenal idea. And you wake up thinking about it, but you say NO to it because you focus on something else.

I like the process of creating, developing, building, and even some marketing movements, in which I understand nothing, but still… But results. It is something that I lack. I hope that focusing should help me with achieving beneficial results. That is the goal.

What do you think about it? May it help to reach results?
