The Best Expression of Love is Time

The importance of things can be measured by how much time we are willing to invest in them. The more time you give to something, the more you reveal its importance and value to you. If you want to know a person's priorities, just look at how they use their time.
Time is your most precious gift because you only have a set amount of it. You can make more money, but you can't make more time. When you give someone your time, you are giving them a portion of your life that you'll never get back. Your time is your life. That is why the greatest gift you can give someone is your time.
It is not enough just to say relationships are important; we must prove it by investing time in them. Words alone are worthless... Relationships take time and effort, and the best way to spell love is "T-I-M-E."
The essence of love is not what we think or do or provide for others, but how much we give of ourselves. Men, in particular, often don't understand this. Many have said to me, "I don't understand my wife and kids. I provide everything they need. What more could they want?" They want you! Your eyes, your ears, your time, your attention, your presence, your focus - you time. Nothing can take the place of that.
The most desired gift of love is not diamonds or roses or chocolate. It is focused attention. Love concentrates so intently on another that you forget yourself at that moment. Attention says, "I value you enough to give you my most precious asset - my time." Whenever you give your time, you are making a sacrifice, and sacrifice is the essence of love...
You can give without loving, but you cannot love without giving... Love means giving up - yielding my preferences, comfort, goals, security, money, energy, or time for the benefit of someone else.
