We all (…presumably) see things that we wish to change for the better.
But,
Change may be taking place so slowly that you can’t see it.

Many major issues are not fixed individually, or overnight.
They are, instead, fixed over decades, or generationally.
People have to die, or age out of power for things to move.

So, you may change it
(…or not)
But you may have to wait, either way.

Which means that you may need to have faith that you are enacting change.
As you may be dead and gone before this change comes about.

“A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it… another instance of the fact, that the future lies with the youth.” – Max Planck
