If you are truly strong, there is little need to emphasize it to yourself or to others. Best to take another track entirely and direct your attention where you fear most to look. You can do this by simply allowing yourself to feel, even to cry, to not have opinions about everything, to not appear invincible or unfeeling to others, but instead to be in touch with and appropriately open about your feelings. What looks like weakness is actually where strength lies. And what looks like strength is often weakness, and attempt to cover up fear; this is an act or a facade, however convincing it might appear to others or even to yourself.
