People mirror our attitudes towards ourselves

People mirror our attitudes towards ourselves I've often heard that people tend to mirror our attitudes towards ourselves. If we're awkward and weird about our stutter, others might feel awkward and weird too. But, if we confidently embrace it as a normal part of who we are, others are likely to follow suit. I agree with that 100 but am unable to "confidently embrace.." I have tried as much as i can but am just unable to. I really need help with that so any advice will be appreciated.
