Jack of all trades, master of none, as the saying goes.
If I could only turn back time, I would master only one genre. Then mediocre on all the other genres.
Mahirap kasi masterin lahat. Weckl cannot be Portnoy and vice versa.
And this is also true not only with genres but also instruments in general. May mga taong nakakapag guitar, keys, and drums pero mediocre siya sa lahat. Now that I'm older I wish I had mastered only one, but at the same time learned the basics with the other instruments as well. Sad to say, when I was younger, I wanted to learn everything. I thought I could be a rock guitar virtuoso, classical piano master and jazz fusion drumming god but this was an enormous, if not impossible, task. Too enormous, in fact, that I think no one in this world can achieve it in a single lifetime.
Choosing one aspect na nga lang e, like jazz drumming for example, is already an immense task to take on...
You cannot be Steve Vai, W.A. Mozart, and Buddy Rich at the same time.
