Decresing distractions who are creating blocks which restricts you to achieve your goal by this method you can increase your focus .
Focus is more important like any other life skill. Swami Vivekananda said once choose one goal and thought about it 24 hrs and 365 days untill it is not achieved.
This type of desire leads you towards success. Big goal may take too much time and patience but it can be achieved by intense focus.
Auther robin sharma said focus is a game chnging for A players. If you want to be a A player you have to practise focus and increase it day by day.
The simple way of increasing focus is keep less distraction. If you have less distraction you have more focus and more distraction you have less focus.
