Helo Mr Perfectionist @f1sh3rman99 
Welcome to the forum. Here’s ex Mrs Perfectionist actually one of them who just decided with a huge help of @aran and the rest of the members of this forum, to throw that perfectionism away and live more freely from then on!
OK, this was a bit of a joke but now siriously.
From my own experiences, perfectionism will do you only harm as you won’t be able to fully enjoy the lessons and this for you won’t be able to learn as much as you woul if you’d take the whole matter at least a bit lightly.
I’m not sure how much this could help you but some of other members say my own journey described in Tatjana - Progress reports helped them to overcome some of their own troubles and difficulties. The story goes from very heavy stubborn perfectionist being determined that the system does not actually work for her to the (kind of) Welsh speaker /(with lots of errors even nowdays) who nowdays is not afraid to speak with anyone and most of all is not afraid of doing any, even the worst grammar or other mistake while speaking.
Apart from that: do what others say, what means don’t endlessly repeat the challenges, don’t be afraid to make mistakes and don’t be afraid to speak loudly if even with yourself or the nature around you for the beginning. You started the journey which would be hard from time to time aswell, but the things will pay off at the end.
Well done on starting your way of becoming a Welsh speaker and welcome to the forum and this brilliant community once again.
Hwyl!
Tatjana
