I'll answer seriously
At first, spite and hatred, every morning I woke up angry and I only did things so I could say to myself "I WON I WON I WON I WON" and I pushed myself to keep going so I could keep winning against the people who pray on my downfall
Now? I wake up because I have a beautiful girlfriend and I do things so I can ensure a great future for us, I push myself to keep going so that our future children know no hunger nor uncertainty of other neccesities
