We should all be grateful for all we have. In our lives today we always drive to have more than what we have already, saying that we are short of what we deserve. In actual fact , is humans do not deserve anything, apart from the human rights such as freedom of speech among other things.
Taking a few moments to remind yourself of how privileged you are, will make you more thankful for what you have and will be a happier person.
For example, if you are in envy due to not having the latest game , if you really notice, it is not that important in the grand scheme of things. Be grateful that you have a roof over your head. Be grateful that you have the ability to be entertained by a games console, when others are not so lucky.
If you see how lucky you really are, the feeling of gratitude will increase in your life. Day in and day out, the way you treat others and yourself will be better. You will feel happier.
