double or nothing?

    well..this is a very hard thing to say..or chose..i am curios about one thing..when to give up..in most of the cases there is a question, double or nothing, double means that u go to the next level, nothing that u receve nothing, and worse, u lose all things u've recived before.

   ..so i wonder myself how do i/we take this decision..now is a double or nothing thing..and i am trying to figer out what should i do.. in most cases..i think that i lose something, and then i quit, and chose nothing, but if i look closley i see that i don't recive what i need, so i want to recive more..

    ..but if it's about luck..this is a problem..i am not chuck norris to say, "i was lucky once, i'll be lucky twice"..the luck we have, is luck, this depends on what? i'm curious..most of the people say it's the attitude..but i tell does people that that is not enough!..all i can se is that..if u want to win the game, u must play it!

   ..sometimes when i need luck, i don't recive anything..sometimes when i don't need luck, i recive twice as luck i need.., in most cases when i have something, the chance of reciving/wining/having luck on the thing i have, much is bigger that in the case i do not have that thing, so strange..all this things..they give me a thing to think..

..so..double or nothing?
