The following quote helped me a lot: "The professional knows that the mundane physical act of sitting down and starting to work, sets in motion a mysterious process that produces inspiration. The amateur waits for inspiration, the professional knows that it will come after he starts. The professional therefore acts in the face of fear, when the amateur fears a big creative endeavor he waits for the fear to disappear,…
Oh boy, I enjoyed that. Everytime I sit down to face a nasty problem I get a little sick, but as I start working a flow slowly starts to build, and before I know it the Starbucks I'm at is empty. I wouldn't consider myself a professional, but I know how to beat my own inner dialogues it seems
Sometimes I'm dealing with a problem that is really complicated and I tried to solve several times without success... I can feel the resistance in bed, when having breakfast and before I sit on my chair and fire up vim to go to that very block of code. It also tears me apart to go to work and leave it unsolved.
Resistance drags us down really, really bad. It makes it difficult to go back to working on a problem.
Not a professional here, but boy this is the point where amateurs quit and that's exactly where I feel the urge to quit too... but somehow I just don't. That's where it clicks "I have to find a solution to this somehow!". Maybe it's a bit of ego but I don't drop something I started[1] and when I finally find the solution, it's almost orgasmic. I feel like I'm the biggest man in the world, and that's my drive to keep moving[2].

[1] Unless it becomes crucially destructive and is clearly harming people, but I guess you get what I mean.
[2] I don't want to make it over minimalist because there's a lot more to it, but I'm referring to this specific motivation building block (I believe motivation isn't just an isolated urge to accomplish thing, but rather several `blocks` that together compose this `will` to do things).
