: the state of being mentally and physically satisfied with things just as they are
: peace of mind; satisfaction
: a happy or pleased feeling with one's circumstances
It is comforting to be at place in life where you know you can handle whatever comes along. You've cleared unnecessary things and exasperating people out of your path so that you can go your own way. That's contentment.
Some people always strive to be somewhere else or someone else; they will never be truly content. You have to be comfortable with who you are before you can find your way to where you want to be.
Happiness and satisfaction in life come from knowing you are where you belong. That doesn't mean you're stuck in one place, but that you trust yourself to go forward confidently and enjoy the journey.
“When you can think of yesterday without regret
and tomorrow without fear,
you are near contentment.”
“At some point you gotta let go, sit still,
and let contentment come to you.”
– Elizabeth Gilbert
