All happiness

“If anyone would tell you the shortest, surest way to all happiness
and all perfection, he must tell you to
make a rule to yourself to thank and praise God for everything
that happens to you.

It is certain that whatever seeming calamity happens to you,
if you thank and praise God for it,
you turn it into a blessing.

If you could work miracles,
therefore, you could not do more for yourself
than by this thankful spirit.

It heals and turns all that it touches into happiness.”

–  William Law in A Serious Call to a Devout and Holy Life
