Well, when it is said that men don't cry, it is not a literal phrase, it is a metaphor that means that a man should not cry, because he is surrendering and lamenting, but on the contrary he must act to change things. It is a matter of strength.
I think we can obviously change the course of the world, because there is no such thing as a fate that guides us, but we direct the world to where we want it to go, and during the last decades we have been irresponsible to preoccupy ourselves only with the comfort and conformity, and immediate benefit, without ever thinking about the future, and where we are heading. We have reached a point where we have lost control and where we only expect things to happen, feeling unable to change things.
I am optimistic about the future, because I believe that nature can't be changed, because we are part of it, and we are in tune with it, and counteracting it will only harm us. Humans are by nature social beings, and any attempt to avoid this will only hinder the process a bit, but ultimately fail.
Sooner or later, be this generation or the other, things will change. Think that there are 7,000 million people in the world, if you think that way, it is very likely that millions of others, even tens or hundreds of millions, will think in the same way, and when many people are dissatisfied, it is only a matter of time for a change to be made.
