I’m talking about people who had this for likely a decade or more, and now it’s not a challenge for you and it’s been years of it being solved. How?
Introspection on why I was stressed starting a task and changes for each type: -Sometimes ambiguous and I didn't know where to start: break it down, and treat 'getting oriented' as a discrete task -Sometimes I was giving myself pressure that it had to be 'perfect': approaching it via iterations -Sometimes I was just too tired to start: understanding my energy cycles and scheduling to do the hard parts right after coffee. And scheduling it.
Other commenters suggesting great other techniques, but for me the core was understanding and leaning in to the sources of anxiety to know what techniques to try. I'm still not perfect, but getting better.
Obviously does not apply to everyone. Do not self diagnose or self medicate. See a professional!
And yes I did suffer for years, sometimes the simplest solutions are those you come to last.
Once someone tried to convince me that "The Procrastination Equation" described the problem exactly, but to me it seemed to ignore key factors, although I admit that it was nice that it recognized that different people have different issues, so there's not a single trick that works for everyone.
I'd suggest that you try the first exercise from "The Now Habit" (Neil Fiore, 1989):
"The first step is easier than anything a book on procrastination has ever asked of you before: simply procrastinate at your normal level for another week. I will teach you to become aware of how and when you procrastinate. Just observe yourself objectively, like an anthropologist who records the behavior and rituals of a foreign culture without making judgments. Don’t judge yourself or analyze your behavior. For now, just concentrate on becoming aware of your current behavior patterns."
It turns out that it's possible to self-diagnose the problem.For me, this exercise was fairly easy because for years I had been logging my activities in a daily journal every couple hours, so I increased the frequency to every 15 min. What I discovered during this exercise was astonishing to me.
Knowing what the problem was, then I could address it. In my case, the issue was described fairly accurately in chapter 1 of Eckhart Tolle's "The Power of Now".
If it's important, it will eventually get done. If it's not, it will get done when I feel like it. This strategy has worked well for me because I've still managed to produce cool projects in my spare time without stress.
I also find that it helps to identify the source of procrastination. For me, it's usually anxiety in some form. If you can figure that out, find a way to cure it and move forward.
We're humans, not machines. You don't have to force yourself to do anything.
The point of this is: Procrastination psychologically conditions you to hate work, because you do it all at the last second drenched in stress and fear. So massive workload and stressful environment. Sure, there is some reward from making progress towards your goals, but this is heavily outweighed by the negative parts of the experience. Which causes you to avoid work more, which increases the problem and gives your brain another experience causing it to reinforce hatred of starting work. It's a vicious cycle / positive feedback loop, procrastination causing procrastination.
The point of the split method is to train your brain over time to like work. Progressing towards your goals is rewarding! Your brain is built to like achieving goals. With the split method, each work session is much easier. There is no stress of "AAH I HAVE TO GET 100% OF THIS DONE RIGHT NOW". Over time after repeated work sessions 1) are not nearly as stressful, and 2) that leave you feeling good, your brain will start to like work more and more. Additionally, getting into the habit of not thinking and starting IMMEDIATELY on your assignment will help break the habit of procrastination. For me the hardest part was always getting myself to start, so being in the habit of automatically starting has been super helpful. I'll admit though I still don't have some perfect work ethic and I haven't 100% gotten rid of procrastination.
I started this a couple years ago and my work ethic is significantly better. Went from being a 2.7 GPA student to a 3.7 GPA student (moving average GPA each quarter, not cumulative).
Also make sure it's outside your home. If you're able to do other things, you will. And dump the phone somewhere where it's outside your quick use.
Ultimately, IMO, breaking through procrastination takes something like a mental muscle, that can fatigue, atrophy, and strengthen with use. Patience and persistence are key.
