"Relationships of trust depend on our willingness to look not only to our own interests, but also the interests of others."
Have you taken stock lately of which people in your life are "toxic"? Toxic people ruin your self-esteem, drain your energy, degrade you, and often gain their OWN energy from sabotaging you. It may not be consciously malevolent behavior on their part; due to their own problems, it may have just become a part of their personality.
Nevertheless, you have to be aware and on guard, because this kind of toxicity can be insidious and derail your efforts without you being aware of it; it often sneaks up on you when you are not paying attention. We must take a relationship inventory and identify the toxic people in our lives. It might be a family who keeps telling you what you are doing will not work or the friend who keeps inviting you to go out and eat things that are unhealthy even though they know you shouldn't.
I have had people say things like this and then they are first ones to condemn me when I make a negative choice. The reality is that not everyone wants you to succeed. Be watchful for those that are toxic around you.
