it is so hard to definate that meaning, each other will have each perspectives differently. 
until now, I have'nt still beleived it! but someone told me that: you have to beleive that! each others has their own life, only once, and the god also makes your life like this, you have to live with that life presetted. 
you can't choose the way you was born in how is your family, but you can choose the way you live that how it is, the way you are, the way you develop and all your life you can reach.
if you say you can'nt, definately you can'nt do, but if you say you can you can, and may be, you can achieve extraordinally you can imagine.
just writting down something without thinking, lost mind and ...., so crazy!...
