Do I Like Writing?

The more I deal with the world of writing, the less confident I feel about whether I really like writing. Somehow, I had always had this feeling that a love for an art like writing is somewhat like the love for doing any other thing - not as in doing things in order to GET something you like but as in LIKING the thing that you do.
I have seen people who enjoy cooking, say. They may like cooking but they feel the enthusiasm to plan and cook elaborate meals only when they expect to be serving an appreciative audience. I am yet to meet someone who cooks an elaborate six-course meal, and take pleasure in merely having done it, with no-one to eat it. When it comes to times when the cook has only himself to feed, the likelihood is a simple meal or even just a cup of noodles. It is someone who likes EATING, and also knows how to cook, who is more likely to cook elaborate meals for himself, if at all there is any such person who would go to the trouble.
Apparently, someone interested in art is of a different mindset altogether. He puts together ideas, events and phrases merely for the pleasure of doing it - if he were a writer, that is - and, if any more pleasure was needed, he would read and savor it all by himself. Readers may also be grudgingly invited but the man is actually doing it all for himself - art for art's sake, you know.
Which is why it seems to me that I have no right to call myself a writer. I react exactly like the cook. I feel the enthusiasm to write only when I have an audience or expect to do so. Not the same as writing FOR an audience - THAT means that, to carry the cooking metaphor, adding twice the salt that you would normally do if you think that THAT is what will please the eater. I mean more the like of cooking what I like cooking, but cooking it ONLY when I think someone who appreciates it may turn up to eat it.
The only things I write for myself are things like "Do not forget to pay the electricity bill tomorrow, you dummy" and things of supreme literary importance like that. When it comes to writing anything else, I see no fun just in writing it. I mean I have already had the fun when I thought about it, so why bother to type it in, and save it in a document if no-one else is going to come around to enjoy reading it? Which is why, probably, I should never ever call myself a writer - I just do not have the divine passion to pour out words on paper/electronic device, without regard to the possibility of anybody else ever laying an eye on it.
Maybe it is because I attempt to write humor. There is nothing more pathetic than a humorist telling a joke to himself and going 'HaHaHa' about it, with sepulchral silence all around him. Maybe that is what accounts for the fact that there are so few humorists acclaimed as litterateurs in the history of literature. Humorists, perforce, have to be Philistines - ever seeking an audience - while the rest can soulfully pour out their words just for the pleasure of writing, without a single person sneering at them.
Now that we are all agreed that I cannot really like writing, I can proceed with writing - and seeking an audience for it - without regard to having to live up to the label of a writer!
