Hello friend, what good advice.
And indeed you have hit the target. I always say that in Steemit and in life the key to success is the "Law of sowing and harvesting".
If you want to be voted, vote.
If you want to make good comments, you should make good comments.
If you want someone with a high SP to vote for you, try to increase your SP and vote (show your commitment).
If you want quality followers, be a quality follower.
And so, the list goes on.
A hug, Blessings.
