Welcome! As I tell every new person who joins this great community, curate, curate, curate. Read posts, comment, and vote. If you can do that consistently every day, your account will grow in no time, especially since you already have a good stake going. More than that though, is you'll be doing what good ol' Warren says above: you'll be reading. 90% of my ideas come from reading other peoples' posts and commenting on them. If you spend a few days reading and commenting, I virtually guarantee you'll come up with at least a couple good ideas to write about yourself.

Good luck and I look forward to reading some of your stuff in the weeks ahead.
