Money, mostly.
Of course it is Money that's why it is called Work because we are being paid lol.
the question is another from Money in which already given when the question was given.
Then i would say, Only Money nothing else work sucks life fucks.
instead of teaching you but it seems you only love money...
I'm sure you don't have children and a wife so your motivation is only 'money'. later if you are married later hopefully you can change your motivation and make your little family your motivation to work hard every day.
