Both "to keep learning" and "to apply ~" are my one goal.
So you are saying that in below sentences, sentence B's are correct and A's are wrong?
Sentence A: My goal is to save money and become a millionaire.
Sentence B: My goals are to save money and become a millionaire.
Sentence A: My goal is to eat one carrot and drink a glass of wine everyday.
Sentence B: My goals are to eat one carrot and drink a glass of wine everyday.
Sentence A: My 2019 new year's resolution is to keep working out and lose 10 lbs.
Sentence B-1: My 2019 new year's resolutions are to keep working out and lose 10 lbs.
Sentence B-2: My 2019 new year's resolution is to keep working out and losing 10 lbs.
Sentence A: My dream is to go to Hawaii and surf on the beach.
Sentence B: My dreams are to go to Hawaii and surf on the beach.
I understand that you can interpret "to keep learning" and "to apply" as two separate goals, but the intention of the writer, which is myself, was to group them as one goal, just like in the sentence A's shown above.
Especially, sentence B-2 about the new year's resolution does not seem correct, because you are changing the meaning of the sentence slightly by incorporating "losing" as part of "keep + verb + ing" structure against the intention of the writer.
Do you still think that it is grammatically incorrect to leave the sentence as it is?
