I read that telling someone about a project triggers the same neural responses that finishing that same project would do, and can make you more prone to leaving it unfinished. I’ve started doing my best to keep super quiet about stuff if it’s a project that I really want/need to actually finish. It’s been working surprisingly well for me!
I've heard this advice before, it's true you lose that dopamine hit which can help, buuut I also learned peer feedback and external affirmation is apparently an important motivator for me... by keeping quiet I never had anything to talk about, because nothing is finished, which later morphed into nothing even starting, because what's the point.
It's still good advice but be careful don't end up like I was, adjust appropriately.
The universe appreciates your excitement. My issue ultimately ended up being comfortable to give myself permission to spend time on the things that excited me.
What we need is an adhd pass along. Get 20% through a project? Post it and let someone take it to the halfway point! You might be interested again once they post the follow-up.
Keep an ideas journal. Write down your project ideas. Let yourself go wild on paper. Sometimes getting the creativity out on paper "scratches the itch" and you no longer need to actually start the project
We sometimes take on new hobbies and projects for a purpose other than conventional completion. And that's perfectly ok. We might want to get a sense of what it is like, or achieve some level of recognition, or gain proficiency but not expertise.
For example, I used to do autocross racing and after a couple years I won a podium finish and a trophy in a local race and I felt like "ok cool good enough" and the interest waned.
It is still important to be able to learn how to accomplish goals, though. Because it feels good and builds some self esteem and gives us a chance to learn how to plan better, and improve our ability to stick to something, even if only a little.
I've had to recognize that I have to significantly pare down what I work on, and be choosy about which projects to actually commit to. That's why the ideas journal helps me.
I know I don't have to start everything, won't forget anything, but be able to recognize those projects of greatest interest that I keep thinking about long term. Those are the ones I am going to be able to finish.
