I believe the meaning of life is something different for each individual. I think it's fair to say that the true meaning of life is someone living a happy life. The change is in what makes individuals truly happy. For me i find most meaning being with people who i love and care about, and who love and care about me. To live my life surrounded by such people to me is living the most successful and meaningful that i can. I believe the rest (career, good results etc) fall into place when you have achieve that.
