I did a project once and it came back to haunt me - this is how I got the job I have now:

I was already working for the company, in the second year of my vocational training as an electronics technician when I got a assigned The Project.
In brief, The Project was a kind of measurement automation implemented with some arduinos. I was tinkering with them at the time in my free time so they must've thought 'Hey, great, she can do that, so she can also do The Project!'

Just that I couldn't - after investing nearly a year, getting frustrated because of the lack of time, support, knowledge etc. The Project died quite unceremoniously and I resumed my training normally.

I just wish devRant already existed back then, it'd have made up for some spectacular rants - The Project was fucking nerve-wrecking due to incoherent behaviour by some hardware and I had to battle the whole big, ugly thing more or less alone as an apprentice.
If it hadn't died at the time it did I feel like I would've brutally murdered it with a shovel - that is, if someone actually would've cared enough to buy me a shovel.

But it ended and I let it go.

In the last year of completing this vocational training, my feeling of "This is not enough" and growing boredom with the routines of my future job had manifested. I wanted to go back to university but also continue working at the same time.

I wasn't ready to do freelancing nor did I want to quit at that time - most people there are amazing and I'm still learning much from them - so I asked early for a student position and got one.

And to get some continuity in my work, it wasn't just any student project I was assigned to but The Project. It came back alive, laughing at me, leaving bodies of dead electronics in its wake, after all these years.*

And that's how I got my current job.

*(They asked me if I was OK with it and they dropped the Arduinos and other hardware in exchange for a bit more software. Also I have a team of great engineers which I can ask for help anytime should I get stuck, so I got that going for me which is nice.)
