In the journey of life

"Dance like no one is watching. Sing like no one is listening. Love like you've never been hurt and live like it's heaven on Earth." - Mark Twain

What does it really mean??

well atleast to me, it says,

in the journey of life...
do what you're supposed to do
do what you want to do
and
do it the way you're supposed to..

don't bother about the outcome or outspoken
because you know you've the right the best you could.
