How to do the Riyaz is a common question. Riyaz means, as you may already know, practicing. In this context let me quote Ustad Enayet Khan, the sitar legend. He used to say, "Ek saadhe to sab saadhe, sab saadhe to sab jaay!". This means if a student focuses on one goal at a time then s/he will achieve the goal in time. Like this s/he will go on achieving one goal after another. Ultimately s/he will become a good musician after achieving several goals.
