Nothing is more damaging than the negative feeling of jealousy.
To be jealous is only a crude way of indicating an emotional disturbance, with many causes and facets.
JEALOUSY = TOO LITTLE OR TOO MUCH SELF- CONFIDENCE.
To little self-confidence, makes you constantly afraid that you are not as good as other people, or able to cope with situations that occur. The result is, that gradually you become jealous of everyone around you. The fear that someone close to you will discover this weakness and uncertainty, makes you want to control that person, even their thoughts, and you try to isolate this person, so you will become the most important person to her or him, and thus able to avoid the comparison you fear.
Over confidence can bring the same results: I am right, I know what is best for you, I am so clever that I can choose for both of us, why should you need to consult anyone else, to confide in them, to meet other people?
You only need me…..that’s all!
The right amount of self-confidence comes from a deep understanding of yourself, it stems from the will to improve yourself and leads you to respect other people, not fear comparisons, even draw from these a reason to immerse yourself still further in your inner self.
Think about this carefully, because Jealousy can undermine your choices, can deviate you from constructive thoughts, and leave you at the mercy of anxiety and fear, emotions that are hardly conducive to your progress.
Searching for the right amount of self-confidence will give you a great ability to love and respect others…for what they are, and not for what you would like them to be.
Confidence in our selves also stems from the awareness of our limits:
we are not perfect…but we want to improve. Who really tries to better themselves does not waste time controlling others, and does not become entangled in the dangerous spiral of continuous controlling, and absurd suspicions.

give trust and expect to be trusted,
give love to yourself, and expect love:
without forcing it, without coercion, without inventing absurd chains and restrictions unasked for, except to be rejected, prompting a desire to flee and run free, leaving all jealousy behind.
