be thankful ...

I don't really want to believe in these kind of mails but then I realize that things don't come easy in life. I feel that sometimes despite of our best efforts things don't turn out the way we want them to. So, instead of becoming morose and complain about it, some people try to console themselves by taking things positively and penning down such stuff. Here it is:

Be thankful that you don't already have everything you desire.
If you did, what would there be to look forward to?
Be thankful when you don't know something,
for it gives you the opportunity to learn.

Be thankful for the difficult times.
During those times you grow.
Be thankful for your limitations,
because they give you opportunities for improvement.
Be thankful for each new challenge,
because it will build your strength and character.

Be thankful for your mistakes.
They will teach you valuable lessons.
Be thankful when you're tired and weary,
because it means you've made a difference.

It's easy to be thankful for the good things.
A life of rich fulfillment comes to those who
are also thankful for the setbacks.
Gratitude can turn a negative into a positive.
Find a way to be thankful for your troubles,
and they can become your blessings.
