"Today is the day of the rest of my life – diploma in hand – it’s time to start my real –life career job!"
"Today is the day that you have decided - it’s time to leave the current role you and go out and find that next challenging role – perhaps even a promotion!"
"Today is the day and you have realized that enough is enough - it’s time to find your next role!"
"Today is the day and someone else has decided (due to company results, a change in future direction, etc.) that your role no longer exists and its time you find your next role!"
