There is nothing more depressing than listening to someone complaining about people and what lies ahead. Usually the person complaining is just as, if not more depressed than the person who has to listen to them. If life is talked about as gloom and doom and there is that nothing can be done to stop it, you might as well commit suicide or put yourself into a hospital. This is just useless worry. If you cannot control the event, why think about it at all.
Complaining about life present and future is not going to win anyone any friends. People will run to get away from you. Why? Because you not only want to bring your life down to depressed, you want to take someone else with you.
Life has a purpose and it is not TO COMPLAIN. Life is about people and making a difference with the things you can change. It is also about achieving goals and not staying in total stagnation. When you complain to an extreme, you can stagnate yourself. You set yourself up to fail. You are telling the people of the world that you do not want to deal with the world the way it is.
The world is only a good a place as you can make it. That is why it is important to make a difference. You can make a difference and change yourself with every moment of your life if you care, but the only one who can do it is you.
