Strive to not lie, especially with what you say to yourself. As you want to be able to find what it is that engages you the most in the present, what captures you, and you can only know that if you can trust yourself with what you feel. Figuring out what the truth is seems far more difficult, but we, humans, generally get a kind of gut feeling when something were doing is wrong; listen to that. That is, whatever sounds like a lie, don't say it, don't do it, and don't act it out; avoid it.
When you find yourself clicking away, skimming, not reading, beguiled, ask yourself: "What is it like to be fooled? What is it like to keep clicking away? What's it like to not read something in depth or to read a book?" Ask yourself questions about your current context. This creates a frame where you're viewing yourself viewing something and you're able to question it and step back, aiding yourself in questioning actions, thoughts, and such.
Procrastination seems to me to be a combination of a lack of engagement and lying, or self-deception. So, as Jordan Peterson repeats, we must watch ourselves and see what were doing. If we can figure out what engages us the most, what causes us to enter mindless repetition, we can do something about it.
A trick I've recently caught onto is that when I'm not engaged in something that I feel should be engaging, I observe that feeling and negotiate with myself, and attempt to say the truth. An example being "I really wish I was interested in this math book, everyone else is. Well, I'm not. How about I say the reason for reading this is to start something and finish it, and that accomplishment generally gives me a good feeling. I can do that." - You cannot be a tyrant towards yourself in my mind. You can, but what I experience is failure when I try something of pure will, as will is either distracted or lost. Instead I come up with some reason I can be happy with and I ignore whatever lie is being said in my mind.
As you give yourself reasons, you'll come to accumulate obligations. I don't believe in setting "small goals", as for myself, I aim to an overly high goal, as that falls in line with aiming towards god (in a symbolic sense). With your accumulation of obligations, you'll come to see a need for a routine, a life sustaining one. This boils down to basic advice such as a good sleep pattern, eating meals, drinking water, doing certain things for certain amounts of time etc.
Now, with all that said, you might think "I can't do this, and it's probably bullsoykaf." The thing is, try it, see how it works. Take a leap of faith in aiming towards god and the good. It's not motivation, it's work, but you'll be a lot better than you currently are which I hypothesize is a nasty state of nihilism.
Do not try; do.
