I'll do my best and give you my perspective.

1. Reward-based social and content platforms will necessarily rise in the near future. Steem will either be one of them or watch newcomers succeed while slowly bleeding out.
   So far, the opportunities for growth have been traded for cash. And the weight at the top is proving a burden for the base to carry. Next year will decide it, possibly just the next six months. A lot of expectations are riding on the coming hard forks. Which can't come soon enough.
   Now me, I am a pessimist by nature. It's going down. But I have not found a likely challenger either. There is still time.

2. From what I can tell by reading your posts and checking your activity, your approach is fine. In fact, you are doing much better than I could.
   Personally, I would never keep up posting daily, and I doubt it is necessary, either. If you realize it's becoming a chore, by all means, slow down, stop, recharge, re-evaluate.
   And obviously, you should be posting about whatever you find interesting.
   I realize I am turning your own advice on you. I will apologize for that. It was good advice!
