Time and life- what is important?

One day we will realize watching behind ''time is really short''

Someone says to me, life should be full of enjoyment. We should play more games, eat more delicious food, make more money and spend the life in a smooth process. In a perspective this attitude may be perfect, but in natural and true perspective- this can't be. If we live our life in vain, then our civilization will stand still. At a time, none of us can survive. Because we would have destroyed all natural resources then for our enjoyment.  For an example we saw the situation of environment because of the factories of developed countries.
In ancient times, there was limitation of enjoymenyt; man has to earn his livlihood through hard working, Although they live in peace, they breathe in fresh air. But in present time? We have lots of money in banks, but have a weak health.

Time is too slow for those who wait, too swift for those who  fear,  too long  for those who grieve, too short for those who rejoice but for those who love, time is eternity- collected.

On the other hand, We did not come in this earth only for eating, sleeping and enjoyment. We have a great responsibility. The almighty Allah, the creator created us for his worship. If we worship, we will get jannat and eternal life, which is more important than so called temporary enjoyment and happiness.
Our life span is too short to be counted according to the whole universe. There is a famous proverb that we all know: ''Time and tide wait for none.''
We have to maintain our whole life remembering our short period. We have to straight forward after selecting our duties, ends and means.
One day we will die. But our work, if it is valuable for mankind, will survive.
