50 looks at the mirror.

I check out my bank account and remember why I work. Keep the money coming in so I can keep nice things around me and do the things that I enjoy without having to worry about the bank account.

I get motivation from the challenges I encounter everyday.

I open my StatsRemote, click on the monthly summary and pretend they were today's stats. That keeps me motivated.

lack of motivation on business related stuff hardly ever happens to me... it's more household related things... especially when i have to deal with deadlines of 10 projects (mostly non-business btw) at the same time... then when i've some spare time, doing dishes of a week is _hard_...
but for me, the laziest situation i can imagine is sitting behind my computer... then work is a small step. when i really don't feel like working proactively i read articles, messageboards etc. which brings me new ideas, which keeps me busy forever...
