“One bad day doesn’t mean that you have failed and you should quit. It simply means you had a bad day.” 

“Don’t let the bad days make you think you have a bad life.”

“Without bad days, how would you be able to know what a good day is like? So be grateful about your bad day, it means that a good day is just around the corner.”

It takes losses to appreciate wins, sadness to happiness, failure to success, bad to good, ugly to beautiful, and most importantly, BE GRATEFUL!
