I think that the present is the most important thing we have in life. Making the best out of the present momement and try to make my life a better one is what keeps me going.
I try to think of my life as a video game :D.
I make tasks for my self to achieve and then I see the results of those as a reward.
It's really easy here on Steemit since your activity and engagement is rewarded with votes and better reputation.
So the short answer, I live for the now and to make my tomorrow now a better one.
Of course my family too but they are included in the now =)
Wish you and your family all the best! Good luck on Steemit)
