I also believe that STEEM can change the lives for many on this planet. This is only the beginning. Imagine if the price of STEEM was 20$ or even more. All the apps like D.tube seem to be doing fantastic as well, which is good for this STEEM blockchain as a whole!
I agree that writing daily is great for personal development. Although it could start feeling like a chore and become less fun after a while. I think it's important to take a few days off from writing when you're on a long streak.
If you're looking for fun ways to write, you can try the 20 minute challenge. I've done it a couple of times so far and it's a very nice change from the regular writing...
If you're up for the challenge you can check out my post about it.
