Meditation is a process of training and transformation. Just like a muscle, you have to train it regularly to grow. Resistance gets in the way such as lifting heavy weights at the gym. Meditation is the gym for the mind which we neglect.
The hustle and bustle of daily life rarely opens an opening to experience the strength and stability necessary for meditative practice. Therefore it is important to devote time itself for meditation, even for 30 minutes a day. If you can spare more time, more is better.
Practice at the start of the day gives you a headset to the day and the effects can permeate your outlook and approach to the thing you do well as to your relations with the people around you.
With meditation, it allows you to see the events in your life within a larger perspective. Little by little, you can change your habitual day of being and you get to understand reality and a finer understanding of laws of cause and effect.
