On planet earth exists the triplex of variabilities.

The first represents irreversible past possibilities.

The second portrays the present available potentials.

The third stands for the future of multifarious uncertainties.

The nature named the triplex yesterday, today and tomorrow.

Yesterday pictures the past prospect and its problems.

Today presents the present possibilities and its problems.

Tomorrow points to prospective potentials the future can bring.

Yesterday represents the past and its shadows.

Today once depended on the forever forgone yesterday.

Failure in getting rid of yesterday's shadow may affect today.

Forgetting the past yesterday increases clear vision for tomorrow.

Today is the day once desired and long awaited.

Today will soon pass into a day called yesterday. 

Today's success can only result from diligent move towards tomorrow.

Tomorrow hence represents the future for which goals are set today.

Challenge:  Work hard today, forget yesterday, focus on tomorrow’s great achievement.

Prayer:  Heavenly Father, help me to put yesterday behind me and to labour today for my future.
