what skills do you think are worth mastering in life?

I think it would be socializing with people. That would be the best thing. through socializing, you can share and you can learn as well.

Communicating or Mylotting. Lol :)

I feel that one needs to assess one's own aptitudes first.Then you should be aware of what is needed to succeed in the world [this is from a career point of view]. Only then mastering can be thought of.Now , for example, if you ask me to master Calculus I would run a mile. So,based on proper self analysis and focus, your efforts at mastering must be channelled in the proper direction

i think communication is the one skill that everyone must master in life..because without proper communication skill you might not be able to express what you are about to say and share things..

Hi. I believe that it really depends on the interest and capabilities of a person. But for me one should really develop and continuously improve his/her interpersonal skills. I must say that I am lacking on this aspect and I envy many successful people who are really good at interacting (either thru speaking or writing) different types of people around them. The world is constantly changing. Gone were the days of giving much attention/appreciation to job titles alone such as "doctors," "engineers," "accountants," etc. "Multi-tasking" is "IN" nowadays. In-demand are those people who are practicing "multi-profession" like a "doctor" who is also a "writer," a "speaker," a "consultant," an "educator," a "businessman," etc.
