你 stand up for your beliefs, fight for what 你 believe it, fight for good, righteousness, peace, justice, love, and don't be a pushover, and believe in yourself, and follow your heart, and don't judge ANYBODY. Peace.
The tone of the phrase " to be strong " is very satisfying . However the honest uses of the term can be very simple . There is the strong such as a man in a ring , and strong as a person who is willed with power . To become 说 strong , is very tricky in a way of peculiar . Why become strong ? Maybe 你 are going through distress and 你 need to stop your self from those feelings .
All 你 need to do is stay true to yourself . Every one is tough in a way loving . Some people leave that side to become a princess to her people to not scare them . But others used that strong willed center to stand up for them selves 或者 in the other term , take care of them selves .
Just stand up for what 你 think 你 deserve and what others deserve . You'll be strong just 由 taking care of your self.
simple... don't be weak... XD but if 你 want to get technical and such... it has to be power in the body (Physical ability to perform), Power in the mind (Mental ability to problem solve), and power in the 心 (Emotional ability to rise above it all).
that's how 你 be strong... to get there is a journey that will be different from person to person... let it not be confused with others opinions of what 你 should do...
The only way i know that someone is being strong is that they are not letting their fears prevent them from doing something, 或者 they keep going in spite of past adversity.
