To me, happiness is knowing what I want and strive for it!
Honestly, if you have a passion to live for, to strive for, then you would forget all hardship no matter how extreme it could be. We only remember shining and happy moments that come with it. That is how I am, too! It could get super harsh at times and really sad at others, but truthfully I only remember the most wonderful things thinking back!
Every morning, I always tell myself this: "I love my job. I love my job." That is what keeps me alive day by day
