I’ll give a bit of a different view. I don’t think it’s always a great thing to dream big. In fact I think it can be harmful to us at times. It’s not just about struggling to break things down into smaller parts or finding the time. Some things just can’t/won’t be done successfully for all kinds of reasons.

Big dreams often need cooperation with others, resources beyond our means, etc. Breaking things down into smaller parts won’t make these issues easier. If we could all raise millions for our business ideas, for example, we would. Some photos try and try and try to chase their dreams and goals for years, and never succeed or even get close.

Dreaming big isn’t bad, but keeping your expectations grounded to reality is an unfortunate necessity for your own well-being.

my interst will probrably change to something tommorow which is annoying.

The last line triggered me to write some “feel with you”. Dreaming big, or thinking big, can actually be a gift. Big inventors, philosophers, people who build companies – they all are/were capable of thinking in bigger terms than what they could accomplish themselves or in a day.

As others commented, a plan should be broken up into smaller “achievables”. It might be less simple than that, though. The problem comes with a lack of persistence, or even a perceived iniability thereof.
This could be traits in the neurodivergent spectrum. Breaking a process up might be a no-brainer to you, but then there are perhaps a lot of things to get done before even starting with the project itself (like needing to acquire the hardware, or funding). If your (main) interest is constantly shifting, and you will have the next big idea tomorrow, then it’s hard to get anything started. Having to accomplish a lot of small goals, while being constantly rewarding to some people, can also be constantly distracting for others. The end goal is just so many little pieces away, and any small task can get your interest astray because that thing that brought the reward is now much closer than the big goal.

As someone who suffers from the same problem, my understanding of what it would take is this: A constant motivator that can direct your interest back to the one big thing again and again. I think what would help is to not do it all on your own, but find other people who have the same kind of interest and keep close exchange with them. The primary goal is not to get the big idea manifested at all costs, but to keep motivated to pursue the path that leads there, while also allowing you to switch your attention to all those other things. Like-minded people who go the same path could be that constant motivator.
(… Yes i’m aware there may be other issues as well, like the thing one has in mind being out of the ordinary, or being afraid of being amateurish)

If this resonates with you, feel free to PM me, or come to the [email protected] group that i started (and have yet to get going, sort posts by “new”!) specifically for such purposes.

Getting into the habit of breaking your dreams into actionable steps and then performing those steps is the single most important skill you can learn in life. What can you do today to achieve your dream? What will you do tomorrow? One day you will stumble across something that truly captures your interest, and when you do all the practice you put in now turning your dreams into things you can do will come in handy. Dream big, but don’t stop at dreaming. Learn as much as you can about everything you might need. Your YouTube career might not make it, but any skills you pick up in video production and SEO might be helpful down the line. If your dream changes tomorrow but you learned a skill today, then it wasn’t a waste.
