Use Positive Self-Talk

One of the simplest, most popular and most effective techniques used in self-esteem therapy is positive self-talk. That doesn't mean that you have to ignore all of your perceived faults or pretend that they don't exist - instead, you simply have to think of three different things everyday that are positive about yourself. That doesn't even mean that you have to like them - it just has to be three objectively positive things. For example, maybe you spend a lot of time helping other people. Maybe you're caring. Maybe you're simply a "nice" person. Whatever it is, write it down - and remember that you can't use the same quality twice.

Soon, you'll start to notice patterns emerge - common themes and common positive qualities that other people recognize in you.

Fake It

If you don't know or can't think of anything good about yourself, try your very best to fake it. Wear the clothes that make you feel sexy and confident. Choose the makeup that gives you a swing in your step. Slip into a pair of heels, or, if you feel sexiest when exercising, your prettiest gym gear. Fake that you feel confident and it will come, eventually. You just gotta believe!

Don't Focus On Weight

The number on the scale is something that we all have a funny relationship with. For a huge number of women, your weight is either too high, or not low enough. It's rarely ever the perfect number. The same goes for BMI - if it's even a little bit too high, it's really easy to demonize yourself and to put a lot of pressure on yourself for not being the "right" weight. But science has long proven that BMI isn't a realistic indicator of your health. Neither is your weight.

Think about how you feel, how your clothes fit and how "well" you are, rather than the number of pounds that you weigh. You are worth far more than that number on the scale.

Hold Your Head High

Slouching and ducking your head sends out a very clear message to people around you - that you're not good enough, worthy enough, pretty enough or smart enough to walk and stand with your head held high and your shoulders back. There's a very good reason why we call the signals our body sends out "body language" - these signals give other people information about what and who we are and how we feel about ourselves. It's important to think about how much your perception of yourself affects how others perceive you. Feel good about yourself and others will respond in kind.
