There is a fine line of difference between sacrificing comfort and sacrificing happiness.

“Sacrifice today for tomorrow”
It means sacrificing comfort.
Not happiness. 

Quit that toxic job.
But chase one that challenges you. 

Quit that toxic relationship.
But chase one that teaches you love 

Quit that undesired college.
But chase people different from you.

Happiness is a daily choice, which we must make. Comfort is an addictive choice, which is what we must give up, if it binds us to not grow. Knowing the difference, is what makes us wiser.
