I've set some goals for myself, and they are my drive.
Some of them are that I want to reach 1000SP before any widthrawal, I want to write stories which will get curied (at least 3 of them), reach 200SBI, etc...
I believe that you've got the point. My main drive on Steemit is to reach my goals, and in the process if I meet interesting persons, that is just a bonus :)
