Life is what we call it when we can feel, when we can live to an extent were we fail to understand the universe. we all have no chance to understand in the lifetimes given to us by god. Life is simply a way to stall us from getting into the true meaning of exsitance, we will not know what that is untill we understand life, but to understand life you must have gone through death and find the true meaning of exsistance, which concludes that it is impossible to understand that which is impossible to reach.
The only true emotion is love, love is the secret to life, without love you cannot attain "eace" at mind.
It depends the moment and the situation that you are living in
As well as how you handle yourself in that situation. And how you perceive it after it's all said and done. You have the ability to change (Even if it's only a little bit) your situation. Attitude is everything.
