Almost everything we do requires a level of of focus and attention of some kind from reading, writing, driving or even just watching the TV. In an age of the internet, constantly pinging mobile phones and the multi tasking lives we live now, it seems to be coming at the expense of our attention spans.
One of the main elements of mindfulness meditation is the ability to detect when your mind has wandered off along with the ability to bring it back to the focus of the meditation. As you develop this skill through practicing more mindfulness and meditation you will notice improvements in your ability to focus on anything that you are doing, saving your time and improving sense of achievement when tasks are completed sooner.
Mindfulness intention is to get your mind to focus on only what is happening in the present thus training your brain to focus. As mindfulness meditation accepts that your mind will wander off and lose attention from time to time it also helps train your mind how to quickly refocus too. So by practicing mindfulness meditations regularly you will you gain better abilities to maintain focus and be more attentive to the task at hand.
