People can certainly decide that certain activities aren't their thing.

I don't want to push to give presentations at international events is certainly a valid decision for any of a number of reasons.

So is preferring to spend more time on coding than managing/mentoring/etc.

But it all has consequences and some branches will lead to more promotions/money/etc. than others. And you may be perfectly fine with that. But go into with eyes wide open.
