@Nikosgarofola Look, if you never doubted yourself, even after convincing yourself of it, then props you, you have really conviction. But that's the whole point of strong conviction, because not always you are able to clear your own doubt event after finding some conviction, you could always doubt yourself and falter especially at the face of criticism, even if you heard it 100s of times. Might sound stupid or not, but people can't help, even if in certain moment they had found conviction, that doesn't necessarily mean that it would hold up over time, or even if that actually convinced them deep down (not rare for people to say one thing, but feel differently). And if you aren't 100% convinced, you can't really help but doubt it.
