The meaning of one sentence

The paragraph below is from a famous book, Art & Fear, by David Bayles & Ted Orland.

I just want to ask you what the last line -What you end up caring about is what you DO, not whether the doing came hard or easy- means.

First, I thought this sentence means "What you should care about is what you DO, which is important, not whether the doing came hard or easy, which isn't important."

(The writer is saying to make art come to you, you should care about what you do, not whether the doing came hard or easy.)

Next, the sentence seems to me a whole lot of different, that is, "You just care about what you do, which isn't important, and you don't care about whether the doing came hard or easy, which is important."

(The writer is saying to make art come to you you should care not about what you do. Instead you should care whether the doing came hard or easy.)

Can you tell me which is right, first or next?

Artists get better by sharpening their skills or by acquiring new ones; they get better by learning to work, and by learning FROM their work. They commit themselves to the work of their heart, and act upon that commitment. So when you ask, “Then why doesn’t it come easily for me?”, the answer is probably, “Because making art is hard!” What you end up caring about is what you DO, not whether the doing came hard or easy.
