Actually I wanted to say
failure may come in life, but a successful man goes ahead to reach his goal with enthusiasm with losing hope. I believe that you are trying to say,"...without losing hope."
Our university teacher saw it and make corrections but he didn't mark there. The topic of the essay was A Successful Man
And next, I wanted to say 'I can not come to university science I feel bad.' to one of my friends.
I still don't understand this part. Are you trying to say that you cannot attend a class or that you do not understand science?
Thank you...
