Best for what?

How can you know where to start if you don't have any idea where you want to go?

Why wouldn't you start with the instrument that makes the music you want to hear?

Why wouldn't you start by trying to emulate a musician that sets your fields on fire?

Why wouldn't you start with an instrument that you think you could spend a lifetime with?

Why would you start with an instrument that is basically a musical dead end like a kalimba?
