Always get out into the real world to meet and speak to people, and take both media reports and stories on social media with a healthy dose of perspective and sceptism.
There are people across the political spectrum and of every belief who have vested interests in sowing the seeds of discord.
Sometimes the one you think is your friend is in fact a foe, taking advantage of your naivety to forward their own agenda. Sometimes the one you’re told is your enemy will turn out to be your advocate and protector.
Get out of the echo chamber and go out into the world. It will make all the difference.
