"SL is a place of fantasy and wish fulfillment. It’s a place where we are free from the constraints placed upon us by the real world. Not only can we choose how we look, but we can choose roles to which we have no access in our real lives."
For some of us , role play will make everything true they wished for, for others it is only a search for themselves, to find out their real "me".
In the comments of this article, Wolf Hartnell (also read his blogpost!) wrote an interesting view on this topic, which I believe, is a pretty good definition:
"Life is (among other things) an ongoing journey in self exploration. The trouble is that we are so emotionally invested in causality. We see our present selves as being determined by our past decisions, and so we hold onto that past far more than we should. Second Life offers a tantalising opportunity that few allow themselves in RL - a new beginning, a chance to be another “me”, or even many different “me”s. For those who are most “settled” in their RL selves the differences are often subtle and SL merely a wonderful way to meet new people. For those who wonder, not necessarily unhappily, what might have been, or who else they could be, SL offers the chance to try and find out.
Most psychologists agree that fantasy is often a healthy way to explore ourselves, provided that we retain a sense of core identity throughout and are ready to learn and grow from the experience. It’s a dangerous path though, because what happens if we find out that we (and others) prefer some other version of “me”. The strong will take that and change their lives. The others? Well we have probably all met one or two of those in SL - perhaps its truest “residents”, lost to RL but for food and sleep. And what do they do when their SL fantasy turns out not to be what they wanted either?"
It is a dangerous thing, Second Life, as you can read in this article and in the comments of this article. You must be very strong to keep both worlds completely separate. For me it will keep being interesting to meet new people and still learning different things, which I was never able to do, before I logged into this virtual world. But to be honest, it is a difficult, dangerous world, where, every day, if you are not careful, can encounter situations, which you did not want to happen, because of misinterpretations and wrong communications, and makes your second life a nightmare instead of a wonderful fantasy world.
