Am I the only one that likes doing things alone?

Yeah you're alone
But not the only one.

Nope, not true. You're not alone.

You just need to find someone like you, is it me? maybe

I think both working alone and with others has its pros and cons.

When I work alone planning is a lot easier, since I don't need to SCRUM or anything like that to keep everyone informed.
Making big decisions mid-way through that changes the project is more acceptable. at least technical-wise, I don't think the client would like it otherwise.
Plus I don't rely on others, which can be a pain 😋

But when I work with others I have more motivation.
And with more minds you can come up with more ideas.
Plus you can learn from each other, and it's much easier to solve a problem together.
I also really like the company of other productive people.

> am I the only one...(anything)
No

You're not alone my introvert friend.
