mention are things that are optional

All of the things you mention are things that are optional. As you say above it's a "feeling" that you must get them done daily, but it's not required or imperative. Your character will not degrade if you miss a day, you can do them the next day. You can do all of them in one day, or you can spread them out and spend some days doing BGs and another doing dailies and another doing professions. It's up to you on how much you want to squeeze out of the system and how fast you want to get "there" wherever "there" is.

If it feels like a chore, it's because you've created a "chore" list in your head versus asking yourself, or world of Warcraft "What do I want to do today?" If you really feel burnt out, take a break. Take a day or two off. Play an alt. Sit in an inn and wear funny hats or sell skulls to tourists in the city. Be creative. The game has a lot of features baked into the various systems that are there for you to use or not as you wish. But, there are a lot of other things that aren't hardwired into the system that leave you open to a variety of activities. The only limitations are the ones you place on yourself or what you perceive are there based on a larger community perception.

In the end, you just need to remember to play it your way as long as it's what is fun to you and makes you happy.
