It’s a bit of an unpopular, defeatist sentiment (especially in this web-world of pinspirational quotes and nature pics) to accept limitations. Throwing your hands up and saying ‘I can’t’ tends to come across as either defensive, or is read as a need for some reassurance, or as fishing. This not any of those things.
If you’re lucky enough to have been raised in a household where the attitude has always been that nothing should stop you, that you can and should be able to do anything, then admitting that you have limitations to abilities can be a bit of a head-f*ck, actually. Genuinely. Not being able to do something comes with the additional shame of thinking you should be able to do it.
Not being able to do something when you really, really want to be able to do it, is worse.
