It may sound arrogant, but this is what I believe.
One can change the environment around them.
People will influence people, you can spread ideas and by doing,
people will buy in from your action.
And if the environment is too undesired, at least you have the choice to walk away and find another one.
Nowadays, There is always way to get thing change by yourself,
unless you are in somewhere without freedom.
Don’t give excuse yourself to settle in that slum you are in.
