Self improvement.

Self improvement is so important. No matter what is it we are doing, we need to improve ourselves. Just make sure everything done is really useful and not a waste of time. 

Even if reading article from internet, watching television (of useful documentary) is counted as productive things for me because i learn something new from there.

I believe we should not stop learning. So whenever watching or reading something, i will try to see what i can learn from there.
