Yes. It is good to dream. Dreaming without taking action is the problem and it should be avoided at all cost.

Going to have to disagree with you on that one. At least partially.

If you only dream and never get to work on something then it is totally wasted effort.

In my case I have come up with many different dreams. I think about them and work them to their logical conclusion.

Sometimes I realize that it is just something I cannot do and move on to something else.

Sometimes I realize I don't have the capital or expertise to do and again move on.

Sometimes I realize it is just fundamentally a bad idea and move on.

Sometimes I realize I need to be at a different place in my life to do that or lack a key partner to do it and move on.

But when I find it is something I dream of doing, and I can do, then its time to get things moving...or nothing ever happens.

As an example. When I first started on HIVE I really REALLY wanted to make some dApps but I didn't have the programming knowledge, learning that knowledge would take far too long and finding someone with that knowledge was way out of my financial ability. I filed it away as impossible for now.

When vibe coding became a thing? I immediately looked into it and what was previously an impossible dream became a reality so I started...

.... only to have to pause when my wife committed me to looking after homestay children.... but I'll get back to work when they leave in January :)
