Affiliate Marketing Secrets

I had about 3-4 serious websites with over 2500 unique page views per day but those were mobile views. I always thought that it simple as:
1. Make a site
2. Get visitors
3. Put ads
4. Cashout
Once it comes to mobile users I can get them as much as I want so the first three steps were not a problam for me because I am good in site making. So like I said I had serious mobile sites in past but I have never earned serious money not even with 90000 page views a mounth!
But now I wish to make a pc site, a blog site preferably. But I very well know the fact that 7days after I will not earn a single penny. So I have decided to make a blog of what I like and not to earn with it, that way I will not be under pressure of money so the thought “This is not getting me money maybe I should quit!” will not be in my head.
So I was thinking of making a blog of what I like and that is Architecture! I study for it and I am best student in my school and I know A LOT about it. But one problam persist how will I get users to see it? I can easily find mobile users which are upto downloading some games, mp3’s or other content but they are most likely not in a mood to read about some architecture.
So that is biggest problam. I dont want to write in vain, I dont want no one to see it. If I spam on other people blogs I know no one will even look at my blog. They will be all like “Hahah he is spamming with architecture! HA!”
I was thinking of making a facebook page of architecture and sending traffic to my blog that way. And maybe I will put some ads after it gets popular.
So what do you think of my idea? Do you encourage me or discourageme?
Do you have any advise for me?
Also exuse me if I made any spell or gramar mistake. English is not my mother languange.

a day, the sites are affiliate sites earning comission per free sign up plus a attractive bonus for signing up in a popular niche, all the sites have weak compettion and are PR0 with the keyword in the url and few backlinks, my question is would it actually be worth while to own these sites with only 10 visitors a day?
for each sign up I will get 15
