This story from The Book of Virtues, is a memorable tale that serves to remind us that as sweet as it is to anticipate the blessings of the future,  we do best to find reason to treasure the present as best we can, and make the very best use of it, no matter the challenge. The wise protect their happiness by not allowing their hearts to wish they could  "pull the thread". 

Here's how God helps...

"Rejoice in the Lord always; again I will say, rejoice!  Let your gentle spirit be known to all men. The Lord is near.  Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God.  And the peace of God, which surpasses all comprehension, will guard your hearts and your minds in Christ Jesus.

 Finally, brethren, whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, dwell on these things.  The things you have learned and received and heard and seen in me, practice these things, and the God of peace will be with you.

But I rejoiced in the Lord greatly...  Not that I speak from want, for I have learned to be content in whatever circumstances I am.  I know how to get along with humble means, and I also know how to live in prosperity; in any and every circumstance I have learned the secret of being filled and going hungry, both of having abundance and suffering need.  I can do all things through Him who strengthens me." Philippians 4:4-13
