What are the 4 words that mean the most to you?

I'm doing some tile/stone work at my home's entry

thought it would be cool to make a design using 4 key words or short phrases

Here are four I'm thinking about now:

Truth

Knowledge

Peace

Freedom

optional words: Family, Love, Honor, - that kinda thing - of course all 4 would have to have a group meaning in some way - contrast or link

still working out the whole idea thing -

what words are most meaningful to you -

considering using - Latin - or - Greek lettering

four quadrant circle - with four scenes that go with each word -

What would you do?

I wouldn't even mind borrowing ideas from Literature - just don't want to borrow from the U.S. Navy or Marines - or say Welcome - you get the idea - something unique and meaningful
