Life Time Achievement

Time and Tide never stops nor waits for anyone.
As the saying goes, life fits perfectly to it.
Consider
Past - Unachieved Task.
Present - Complete to the best.
Future - Do not plan as tomorrow never dies.
Live life to the fullest for present, do not overlook past or expect future.
If you are able to make out the present life merry, thats the achievement.
Take up the life/task as it comes and complete with joy.
If the same rhyme is followed all through your life, that would be the biggest achievement which could keep you satisfied.
