Hey jayanarchon. Those look like good tips for someone trying to start a business! However, I'm not trying to start a business on Steemit. I'm trying to generate STEEM (as is everyone else here), but that's not the same as starting a business. Those tips would also be good for, say, a beginning investor. But I'm neither a beginner nor an investor. :)
I'll try and re-summarize what I've been saying in my posts for months/years.
I'm a content-creator. Text, images, video, audio, ideas, books, groups, projects, teams, I create content to further my activism. It helps me get my message out, helps me feel like I have a voice, it furthers my cause. You could think of my content-creation skill as a tool I use, much like a rapper might use his skill with lyricism and flow to further his cause.
I've wielded this tool all over social media for a long time. It has always been separate from my businesses, which tend to focus on things like collectibles. I don't invest. I see that as wasteful and harmful competition between the people, not as something which adds any value to the world. I stack silver as savings, not as an investment. The same goes for cryptos, which I see as currencies, and potentially as savings, but not as investments. When I say "investment" I tend to mean capital. I sunk all my crypto savings into STEEM several months ago, and I'm glad I did. That's my investment. I'm not a trader - I don't attempt to accumulate more of something by moving in and out of it. To me, that's corrupt. I see most typical investors as leeches living off the rest of us who actually produce something. (I've gone over this a million times, but you're new, so I'm catching you up :)
So yes I'm trying to generate STEEM (my goal is 15 per week) but I'm not investing and I'm not running a business.
As for your 4 steps to a profitable page, here's my take:

1. Most accounts are over 2 years old
   Yeah, most accounts over 2 years old here are doing well. In other words, most of them are doing well because they got here first. From what I've heard, it used to take a few weeks of clicking and playing around here in order to generate thousands upon thousands of STEEM. New accounts got hundreds of free STEEM. After a while, it got a bit harder to get rich here, and you had to "grind" for several months in order to make it into the club. Now, as far as I can tell, anybody just starting fresh at zero is going to have to wait a LOT longer than 2 years to get rich here.
2. Many have a website and blogs outside of steemit
   Do they? I haven't noticed that. But anyway we have that covered.
3. Pretty much all of them do at least 1 high quality post per day
   We're doing 4-5 so got that covered.
4. Almost all of them are part of at least 1 curation trail
   I disagree with buying and selling votes here. I find it to be corrupt and unsustainable. Hopefully it isn't truly necessary! Like I said, if Steemit can't find and reward quality content, it will die. That's one of the core Steemit functions (supposedly). If buying and selling votes, ie: rigging the system in one's favour, becomes the only way to succeed, the site is already dead. I sure hope it's still possible without resorting to that.

   I think this is a great spot for my meme:
