Many people cant find it within themselves to say anything positive and take pleasure from flagging up someone's shortcomings. Don't make it about you, as these people need to feel superior because they are so insecure and the only way they can do so is project their own flaws onto another person. They do it with everyone.
To build up confidence from within we are advised to put it on and wear it "like make-up" and "fake it until you make it". Although eloquent on paper, such advice isn't particularly useful. Is there anything more practical to help us feel more confident ahead of a nerve-wrecking interview or an important presentation?
When you first embark on healthier lifestyle you're not the only one who needs to make adjustments - those around you have to get used to the new you too. Even though eating a more nutritious diet and exercising regularly are clearly positive changes, you may well come up against resistance from other people and it's important to pre-plan how you'll deal with it.
Women can be more sensitive and think more emotionally. In my experience working with both genders, the women worry if they are worthy and if they deserve it. One client thought if she asked for more she would be sacked because her boss would be cross, and another though he wouldn't like her any more and would make her life difficult in the office.
