My keys to growth (day 25, rep 42.3, 514 SP):

• invest in SP to get compound growth (see how I have done it at: https://steemd.com/@freedomshift)
• post only about what you do best
• resteem posts that will round out your blog - profile
• comment in other people's posts constructively including those out of your primary focus or interests
• help new steemians
• collaborate with the "oldies" or "whales" or bigger fishes" (respectfully)
