"Love just doesn't grow on tree"...
We've all heard the saying "money doesn't grow on trees". That statement is usually said when someone is spending unnecessarily or wanting for things without thinking about the expense. The same is true for love. There is not an endless supply of love, if you are NOT taking care of the love you have. You have to invest in love, relationships, and people if you want to get a return.
Now, I am not saying that you should go invest in things that you know will crash, however I am implying that if you have something you want to see grow, be mindful of how you treat it, or you may just wake up broke.
