Is Impossible always impossible???

Today, received a mail from my friend krish asking me to comment on the following statement,

"Is Impossible always impossible???...or is possible always possible..if the possibility of the impossible is greater than the impossibility of the possible, then it makes all the more sense to pursue the impossibile...if the possibility of the impossible is greater than the possibility of the possible, then will impossible still be impossible???"

I replied back saying:

"I think as the possibility of impossible tends to become more than the imposibility of impossible, then the probability of impossible becoming more impossible is more possible."

Another friend of ours replied back stating:
"Who knows what is possible. Everybody knows what's difficult. 'Possible' is only an excuse to waste time pursuing the impossible."

Awaiting more reactions to this statement.....
