I try to think about how happy and content Future-me will be once the job is done. I confirm the accuracy of this thought to myself by thinking back to how it was in the past when I completed some task that was difficult for me. So I think of an experience where I realized in hindsight that it wasn't actually that bad and that I was worrying for nothing that I might somehow fail. And even with things that ultimately didn't go well, I can still reassure future-me that there was no need to make a big deal out of it, because even my failures have lost their horror over time; for example, embarrassing moments at school, awkward dates or bad presentations at work. All these things are just water under the bridge or at best even funny when I think back on them today - and that's how it will be in the future: as soon as the job is done, I'll be alright, regardless of whether I succeed or not.
