How do I trick my brain into completing a project? I'm making an app that shows which voice actor plays a character in the movie and what other movies they act in. It's useful for me personally so the internal motivation is here but sometimes I feel like I'm making something that's been done numerous times over and I lost the momentum because I'm on vacation with my family now.
I ran into some problems with the project too and getting help takes a ton of time so it's disrupting the rythm too. I wish I didn't have to rely on other people so much but the documentations don't answer all of my questions. I really have to put at least 2-3 projects like this for a portfolio;_; halp
Want and grit. At some point you'll have to grit it out. You have to make it clear to your brain that you want it. Make it personal. Want it not the way you want to have a cookie after dinner, want it the way you want to breathe. Don't even want the project, but want to prove to your brain that you are a rare capable human, able to start and finish a creative endeavour independently.
Make work time scarce and urgent. Having a child has done wonders for my creative output. I used to splurge 6 hour sessions kinda working on something..now I get maybe 40 minutes a day. An hour if I'm creative about it. But heck, does that hour get applied like nobody's business.
Hope this helps, best of luck!
