From A Little Book of Happiness compiled by Ruskin Bond,

The secret of happiness is to find a congenial monotony.
-- V.S. Pritchett

Happiness is not waiting to be found; there's no use looking for it. All we need to do is find the barriers within ourselves that we have built against it. Trust -- in people, in life -- is a good way to begin.

We must be willing to let go of the life we have planned, so as to have the life that is waiting for us.
-- E.M. Forster

Life works upon a compensating balance, and the happiness we gain in one direction we lose in another.
-- Jerome K. Jerome

The adventure is not in arriving, it's in the on-the-way experience. It is not in the expected; it's in the surprise. You are not choosing what you shall see in the world, but giving the world an even chance to see you, to get to know you, and, perhaps, show you just the things you had longed to see but could never find.

Sometimes, when all else fails, a sense of humour comes to the rescue. Laugh at yourself, laugh at fate, and soldier on.

What if you failed yesterday? Today is not yesterday.

The storm is over, there is sunlight in my heart.
-- P.G. Wodehouse

Dear reader, may you have the wisdom to be simple, and the humour to be happy.

If you want to be happy, be.
-- Leo Tolstoy
