There would be no smile without a tear shed,
No true love without a true loss
No life without the thought of death first
No pleasure without a real struggle,
But, once on the top the view is great

Share your love, but not the key (password) to your heart, unless you know beyond doubt that someone truly loves you, unconditionally.

You can win hearts just by your goodness, and lose someone by the expectation of them loving you back. You will find, love will never cease to flow in your direction, if you do not demand it, but demonstrate it.
