There really is so many things to learn

You know, the more I progress on into the semester and ongoing continuous learning, I feel like there are truly so many things that I do not know. From simple to complicated, I feel like that life is such a continuous journey of constantly learning until the day we breath our last.

Even at old age where we start to develop diseases that may cause memory lost. We still need to relearn the things that we already learnt before.

Thinking of such things sometimes gets me a little depressed.....

Cause eventually in the end, everything will be for naught. You will just be forgotten unless you really make your mark in the society and I don't think I can go that far.
Somehow I think back of the things I should have done like a normal person. Studying, being a good human being overall, etc etc....
And I feel like if I don't experience them now, it might be too late later on when I'm working. That is IF I'm working. And when I'm working, Will I have time? By then I'll probably have a family and need to work hard to support them....
So sometimes, I really don't feel that bad just taking a day to do whatever I feel like doing regardless of how childish,expensive,impulsive it may be. Cause if I don't do it, I'll never experience it. If I don't push myself, I'll never get to enjoy the life we only experience once.
