Direct linking CPA

Hi to everyone, I'm Manuel, CPA beginner, I have basic knowledge because I've did two affiliate marketing course (one from big Luca academy) was general into affiliate marketing world, and another one on Native ad's and CPA. I know how create a wordpress website, i know how create a landing page with ton's of tools out there I know it's good using a VPN and spy tools, I've got adplexity as well.....
I'm in maxbounty and mobidea....
My goal it's: grow my little 2,5k $ budget and start doing CPA affiliate marketing full time job,
I'm single, I have flexible minimum wage job that can allow me to keep a good amount of time on my laptop to improve and research....
Anyway, this is my question:

It's a good strategy
promote a SOI offer with direct linking?
I don't mind collect email right now for doing email marketing later, I want just earn some cash buying ad's and earn money, and then invest again and then again and again and again....

i didn't understand
Why put my landing page between me and another landing page of the SOI offer? I don't have the risk that the user that land on my landingpage, get boring to register in anoter landing page and leave from this?

Any tips? Thanks in advance to everyone will reply on this topic
