Just a normal day

Today I have done nothing special.

Good use of the present perfect. This tells me that the day is not done and that you feel like you probably won't get anything done the rest of the day either.

I woke up early, had a breakfast, read some news, have worked and so on.

Don't mix the tenses (present prefect). I woke up early, had breakfast, read some news, did some work and so on. In this phrase I feel like I'd be more likely to say that I "did a little work" since in the first sentence you gave the idea that you have not really done much in the day. One thing to keep in mind about breakfast is that it's a little strange as a noun. Originally it was a verb: to break your fast. Since it was transformed into an abstract noun it tends to be uncountable. The only time you can use the indefinite article with breakfast is when you distinguish one specific breakfast from your normal breakfast. I had a hearty breakfast. I had a light breakfast. I had a big breakfast with bacon and pancakes. If you have not heard about OZDIC, you need to check it out. http://www.ozdic.com/collocation-dictionary/breakfast 

It's like a dictionary, but it gives you the common adjectives that native English speakers associate with the word you type in. For example, a native English speaker is far more likely to use heart with breakfast than to use heart with any other noun (except for, perhaps, meal). You might not even know the adjective because it's so uncommon. But if you are going to start talking about food, you need to know it! 

Probably, tomorrow will be different, there are some issues waiting for me and I need to deal with that. 

Issues is plural, use them. One note about the use of probably here. I feel like it's somewhat unnatural unless you pause and slight raise your intonation at the end of the word. This is a social cue that you have not completed your thought and still have more to say. It's subtle but an important part of the rhythm of English.

Just a normal day

Today, I have done did nothing special. I woke up early, had a breakfast, read some the news, have worked went to work/got some work done, and so on. Despite doing having done nothing special, I enjoyed the day, and the World Cup games were really exciting. Probably Tomorrow will probably be different, as there are some issues waiting for me and which I need to deal with that. I hope to have an interesting day.
