Be not afraid of life. Believe that life is worth living, and your belief will help create the fact.
Love the present, hold on to it as long as you can and live the moments with all your heart and soul because you never know what comes next.
Else youre thinking that your present isnt good enough, remember there's always a tomorrow that will bring hope in your life and fill the dark side of the past. Not exactly fill it but try to shadow it up.
And for the fact that just like movies our lives have a happy end too.. :)
