New method

Earlier I have done a lot of Tumblr projects but never to drive traffic to landing pages. What I'm planning right now is.
-Create new blog for specific niche
-Use my old blogs to promote that new one
-After some active followers start to use link to my LP
-PROFIT?

First I need to find niche that works. Everything what is near to health are easiest one because people that are following you are already motivated to find solutions. So maybe we choose that.
I have huge advantage to others when I can shout my new blog in old ones to get followers faster. Maybe we later do a new project where we start from the scratch.

Let me help you

Like I told you I have tried almost everything and now I'm doing this blog for you. I got good job in construction company and I'm working like a donkey. I earn about 60k € in year and I got little side earnings from my rental business and advertising pays from this blog. I invest all my money after bills to  Helsinki stock market.
Later if this blog got some readers I show some pics and tell you more about it. But I really hope that all you save little bit for the bad day and don't scare to take risk in stock market now it's really good time to buy shares!

Once my friend said to me this. You have to live like etiopian and invest like Warren Buffet to be very rich man.
