I did not get 600 followers in a month. My account is now 120 days old and I have 920F. So I averaged 230F per month. This is a good average and I am confident that it will rise next year. Don't compare yourself to others. 

# How did I do it?
1. invest in steem - so you can give a few cents to your followers
2. post interesting quality content on a regular basis
3. don't ask for upvotes or follows as it will hurt your rep and you WILL get flagged
4. share what you have learned about steem and steemit platform (tips and tricks)
5. talk to the people on steemit, leaving meaningful comments on their content
6. find your niche, the one thing you can do best to bring value for others
