Sun and Moon. Sand and Wave.

Everything in the world is of equal balance.
Every yin has a yang.
I believe this is important to ensure that the Universe is in equilibrium.

You know at which point a relationship becomes dissatisfying?
When it's unbalanced, that's when!
When you give one month's worth of sentiments in a two month's relationship.
THAT is when it will feel unworthy.

So now you have two options :
Give it all you've got and milk its worth for as long as it lasts
or
Cut your losses early - as soon as you feel like you have nothing more to give.
 - not a feel, not a care
Let it go.

Life is short.
Go for what you want. And go for what wants you.
