There's not much for me to add to what the other commenters have said here. Many of us have been hoping that people in your situation will draw from the reward pool less, and concentrate on more on raising the value of steem. You and some others have so much latent ability to do so through your stake, it's more sad to me than anything else when this potential isn't achieved. I believe that one of the primary methods we can all accomplish this is through supporting new and undervalued blogs, not by directing the majority of support to established orcas and whales. It's true there is value to individuals such as yourself holding large amounts of steem, but there is so much more value in getting more of the reward pool to smaller blogs to energize them to keep posting more content, and even possibly purchase more steem on the open market. Any number of the commenters here could help you both maximize your curation rewards, as well as your impact. I've always had the impression that you want to be a positive force, but it's easy for all of us to get locked into old patterns, and that's understandable. I would only suggest before making any hasty decisions, that you experiment with adjusting those patterns and see what happens. You might actually be pleasantly surprised.
