they spend seven bucks on a cup of coffee almost every morning, throw a hundred dollars on some gym membership cards but never show up training, have dinner with some random girl in an expensive restaurant, buy drinks in bars and waste hundreds of dollars... The list goes on and on.
If you are used to this lifestyle, it's hard to go back. Nobody wants to return to a previous status they were before. It's a rising progressive line in life that makes it rewarding and leads us to self-realization. It's not about the expensive coffee, the girl, restaurant or the drinks. It's about the environment you are attending to and how you feel good to be there. It's inspirational.
You won't feel the same if you attend to the coffee shop where the cup of coffee costs 0,50$, giving up on going out with girls, due to it being expensive, or drinking at a cheap dirty pub. Everyone wants to live the best as they can, so I really don't blame people who are trying to do this their way.
In living life, everyone will certainly do what makes them feel comfortable with what they do and does not make other people feel disturbed by what they do, each person has different ways of making themselves happy with what they do so that they are happy. You are right, everyone certainly wants their life to be better than yesterday and of course they do it in their own way.
