I don't know who needs to hear this right now, but I want to remind you that it's possible to change.
It doesn't matter who you are, there's something for which all that's actually stopping you is an incorrect belief about your own inadequacy, nothing else.
Maybe you won't ever be able to achieve at the same level as other people can, or to completely perfect yourself, but it's *always* possible to improve.
You can learn. You can practice. You can experiment.
