Time lost can never be
Time is very precious so use it with caution
Time wasted is a future destroyer. 
A second counts
Every minute of every hour
Counts so don’t throw away
The time you have.
Study with the little time you have
Work with the little time you have.
Truly time lost is not good at all
Time is very valuable so use it wisely.
It is profitable because time lost
Can never be regained.
