Life comes in a package.This package includes happiness and sadness, failure and success, hope and _ .Life is a learning process.Experiences in life teach us new lessons and make us a better person.With each passing day we learn to deal with various situations. Love plays a main role in our life.Love makes you feel wanted.Without love a person could become cruel.In the early stage of our life, our parents are the ones who show us with love and care.They teach us about what is right and wrong, good and bad.But we don't always care about it.It is only after marriage and having kids that a person understands others' feelings. Happiness can bring people a peaceful mind.No mind is happy without peace.Sadness is the cause of the death of a loved one or the failure.But all of these things will pass away. Failure is the path to success.It helps us to touch the sky, teaches us to survive and shows us a specific way.Success brings in money, pride and self-respect. Hope is what keeps life going.Parents always hope their children will do well.Hope makes us dream.Hope builds in patience.Life teaches us not to despair even in the darkest hour, because after every night there is a day. Life teaches us not to regret over yesterday, for it has passed and is out of our control.Tomorrow is unknown, for it could either be bright or dark. _ What's the meaning of the last sentence of the whole passage?
When choosing between "today" and "tomorrow", you'd better enjoy tomorrow. If you work hard today, you'll have a better life in the future. What you can only choose is to work hard today rather than tomorrow. The only choice you make is that you should enjoy a better tomorrow.
