I saw this in the Malaysian Airlines ad, 'Journeys Are Made By The People You Travel With'. And that is totally true.
If you are surrounded with good people, then you are safe. Because positivity and the not so nice, negativity will rub on you. Unknowingly. Us, human beings gravitate towards others.We can't really help ourselves.
If you care about your soul, and would wish nothing than for it to be in a good condition..run away, with all your might towards the other end if you don't want yourself to be called bad by others someday. Lets have great journeys together with people we want to emulate, and say goodbyes to those we rather not.
