When people talk about Luxury, they usually talk about money and all the nice, expensive things money can buy: cars, jewelleries, houses, resorts, yachts, cigars, champagnes, golf clubs and parties. Money is really a good thing. However it is just one dimension of luxury.
The second dimension of the luxury is the time. People who have money, but no time to enjoy the life, because they have to spend all their time to earn the money, are actually poor people. Real luxury therefore starts with abundance of time. Women understand it better than man. They sometime just take hours shopping, not necessarily to buy anything, but to enjoy the time.
The third dimension of the luxury is the emotional freedom. You are free to go to an expensive restaurant, but also free to choose to go McDonalds for a junk food. You are free to get close to a friend, but also free to be happy without him or her. You are free from any negative emotions, but also free to accept them, when they are there occasionally. You are emotional independent from your spouse and kids, but free to love them deeply. You are free to make your boss or customer successful, but also free to leave them, if you decide to.
When you reach all three dimensions of luxury, then there is nothing you will regret when the time comes for you to leave the world, with an eternal smile on your face, completely free.
