Which One?

I always have this huge urge to learn,to get better in doing things, to learn new things, to get myself busy all the time. Because only then will I feel productive,
and guilt free! Even now, I still have a check list on the things that I want to learn in the near future.

It just came to me that all these learning things are only beneficial for myself. These doesn't bring any good effects to other people!

When I'm studying, wherever it is, whether it's in the kitchen, campus, language institution or even in my own room, it's not about the money or the energy that I spent. But what matters most is the time that I've used up for studying by myself.
This means, automatically there will be lesser time allocation for me to spend with my family, friends and, sadly, for God.

Somebody said that I'm self-centered!
I agreed to it!

Other people said that I need to prioritize..
I know!
But the question is....
Which priority is good? Which one is the right thing to do?

I'm young, I have the energy, I have all the resources I need,
and above all I have the determination to do it, to learn!
Shall I continue with it while I'm still young?
Or in the contrary, while I'm still young, shall I spend my time with family, friends, and, of course, God?

So, which one?
