If you spend a few minutes every day doing some very simple exercises of concentration and self-control, it may be of great benefit to you. But so many people claim not to have the time! Well, since they don't have the time to be in a state of peace, harmony and light, there will always be time for difficulties, disorders and darkness.
The one certain thing about life is that humans will be unhappy, sad, disappointed and discouraged. It is less certain that they will be happy, strong and peaceful. Why? Because they all enjoy saying, 'I don't have time'. This is the easy way to justify their laziness and inertia. No time to study or to pray or do exercises. And what keeps these people so busy that they don't have time to devote to their psychological wellbeing and their spiritual elevation? Often nothing more than trivialities. This excuse of having no time might work with the blind and the ignorant, but never with heaven.
