You could use all sorts of physical restraints to tie you down to your chair and force you to sit there. But that probably isn’t what you actually want to do lol.
I usually use a few analogies when talking about challenges and how to tackle them. Mostly because I believe being able to view the problem from “the outside” can give some insight into what is going on “inside” of the problem, IE what you are facing.
My favorite one is programming is like cooking. I believe it works well because both are skills that require just raw experimentation, and dedication to actually learn it. You need to cook to learn how to cook, same way you need to build to learn how to build. You can’t become a great cook just by reading cookbooks, or learning cooking theory. You gotta put to practice what you learn or you forget.
No matter how many times you read about how to crack an egg properly until you do it over and over again, you wont get good. Until you combine that simple and singular action with all the other steps to create a more complex dish than an omlet, you probably will feel dumbstruck staring at your kitchen.
This is probably the same type of feeling you are having trying to build some of these projects.
So what to do then? I suggest building something small. Identify something you can try and try to build it within a time frame. Don’t know CSS? Then build a website without one. Don’t remember HTML, then use as little as possible to build one. Keep reducing until you either get to somewhere you already know, or are bored, then add in more “parts”.
Unlike cooking, experimenting and just trying to do stuff is relatively free, you don’t have to “eat” what you made, nor do you have to buy ingredients or even clean up after! So build, fail, learn and build again. Rinse and repeat and you will see progress even if its brute force repetition.
Good luck, keep learning, keep building and keep asking questions!
PS. I wouldn’t use AI unless you want to never think/learn about what your doing. If you just need something done then sure, but understand it doesn’t help you learn.
