Your Self-Worth is The Value You Put on Yourself
Perhaps it is because we are brought up with the idea that we should be modest and not blow our own trumpets most people tend to value themselves as less than they actually are.
Pause here and review what you have done recently for a few moments. Have you visited a friend who is sick, have you smiled at a stranger to bring a little lightness into their day, have you shared some humour with a colleague at work, have you helped someone who does not have your ability in a certain area, have you made or done something for others (like cooking a meal, or a giving a presentation that enhances their understanding, or giving directions to a stranger)?
There are a thousand and one ways in which you constantly add value to the lives of others. Many ways that you give pleasure or reduce stress for others. All of these can only happen because you have a value. Sometimes this value will be great, at other times it will be small, the important point is that whatever you do gives value to others. You should recognise that you have value and use that recognition to give yourself the gift of self-worth.
You are worth more than you give yourself credit for.
