What Are The Life Lessons Learnt From Being Exposed To The Wrong People?

Sometimes in life we're exposed to the wrong people without having any knowledge or inkling about it, when I mean the wrong people I mean the people who hardly appreciates us, people who wouldn't raise us up, take advantage of our kindness and generosity. In truth the wrong people takes our time away from people who deserves us, it makes us unaware of the fact that we're the game changer which people who needs the opportunity to be better deserves. The right people however brings out our goodwill, our personalities are often appreciated in their existence and we become often fufilled with each and every effort.
Life doesn't come with a checker and sometimes being exposed to the wrong people makes us formed an adulterated perception of humanity the moment we realise that they've been the wrong people all along. Sometimes you see dying people distributing their wealth to the needy rather than giving it to their families or associates, it's because they've realised too late that their attention, wealth and affluence would be all vanity if they don't touch the lives of the right people.
