Whatever the time be, you must do Japa every day. It is not good to forgo it any day.

What a lot of work I did when I was your age! And yet I could find time to repeat my Mantra a hundred thousand times everyday! 

True it is that there is no hard and fast rule about the time of Japa, yet morning and evening are the favorable periods. Whatever the time be, you must do Japa every day. It is not good to forgo it any day.

Please check these: Excerpts from a discourse by our Sri Sri Muralidhara Swamiji

Catch hold of this divine Name and go on doing your work in the world.

Hanuman worked tirelessly for Rama. He also performed incessant Rama japa. We should also be like this.

Nothing we earn today would come with us to the final destination but only the Divine Name WILL

While you concentrate on your studies and prepare yourself for your future, you also need God's grace.

At the same time performing activities without spiritual practices is meaningless. We should learn to be like Hanuman by balancing both types of activities.

To achieve this goal I try to chant His name but am not able to do it continuously because it is involved in worldly activities

Chanting the Name of Răma, Hanuman crossed the ocean! -- and, lifted the mountain!

Mountain sized sorrows melt away like the fog!

Keep Chanting, even while engaged in the activities of the world

One should constantly repeat the names of God irrespective of any activity that he might be involved in

Keep the Name of the Lord spinning in midst of all your activities. Have intense faith in God, and in His Name, know that they are not different.
