Thank you for your motivational message, this has explained some things when you're climbing to success or already successful, there are those who are envious of you and your progress they'd do anything to stop you and when they can't they start physical attacks and start saying lots of bad things at your back. I've experienced such though and i have also felt envious of some people's progress too, it's just a thing we can't stop ourselves from feeling we just have to control how we feel and like you said "we can't allow ourselves to be dominated by thoughts of jealousy and envy".
Thank You! Best Regards
