What I personally believe is that it can only be attained with the help of the good Lord.
I prayed for it once, since then...I am not the same person.
I 'think' before I say things, do things, and it has helped me in a tremendous way.
I do aspire to attain wisdom, but I am not even sure what the difference between wisdom and intelligence and knowledge is. Are they inter-related? I think they are, but what exactly is it that makes a person wise. I think it might be the fact that a wise person can make good decisions in the present day by looking far ahead into the future to guage what is best for him/her? I don't think I have attained that stage in my life yet, but I shall continue to aspire towards it.
