Discomfort in evolving

Is it necessarily true that growth is always uncomfortable? Or sometimes can it be fun?

Sometimes I think I make things harder for myself than they need to be, but then Brooke teaches that growth/evolving can be uncomfortable. Should I view this as a different kind of uncomfortable? Perhaps one is suffering and one is discomfort?
Making things harder for myself = Suffering
Growth/evolving = discomfort
Would that be a good way to look at it?

Does everyone find growth uncomfortable as some people just seem to fly through setting up a new venture or learning a new skill? I compare myself a lot to these people.

I worry that I have used discomfort as an excuse and seem to find reasons to blame external factors for why I quit or for why I was sad and basically wallowing?

I would love some pointers on this topic.
