Do it now:

     Twenty years from now you will be more disappointed by the things that you didn't do than by the ones you did do...Sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.

Mark Twain

     There is a tide in the affairs of men, Which, taken at the flood, leads to fortune; Omitted, all the voyage of their life Is bound in shallows and in miseries. On such a full sea we are now afloat; And we must take the current when it serves, or lose our ventures.  

Brutus in Julius Caesar Act 4 Scene 3.

May the road rise up to meet you, May the wind be always at your back, May the sun shine warm upon your face, And the rain fall soft upon your fields, And until we meet again, May God hold you in the hollow of his hand.

Irish Prayer

It is preoccupation with possessions, more than anything else, that prevents us from living freely and nobly.

-Bertrand Russell
