What's the correct way of using "such" and "such a"?

What's the difference between: incoming, oncoming and upcoming? Could you provide a few examples, thanks.

Decided to improve my skills I'm an IT guy who works in Belgium. You could think that I speak French or Dutch pretty well since both are official languages in the country. However I mostly speak English...and not as good as I would like. A few years ago I studied on my own and managed to pass the FCE exam, and now I made a new resolution: attempt to pass the CAE exam. I already have the basis and, actually, I'm not interested in improving my grammar skills since they're the topic of the exam. I just want to speak English better and understand native people as well. For this reason I decided to be back on italki. I already used this platform and found it very useful to share my texts with the community. Since I don't know what to speak about in this first article in my road to CAE, I'm simply telling you all my story. If you're reading this post, probably you're a native speaker and can help me. I'd like to improve my vocabulary (wording, expressions...) and listening skills. Despite I'm not much interested in grammar, I still have a few questions for natives but, well, we'll address that in the coming posts. My creativity is not good enough to continue to write, so that I'll close this text with the hope that you can help me with my English and I could help you with your Spanish. Best.

Payment of taxes: fixed or variable rate? In many countries all around the world, people pay taxes depending on their earnings. That is a fair system considering that not everyone has the same resources (money, properties…). Normally, a percentage of your incomes is destinated to contribute with the society. As much resources you have as much you pay. On the other hand we can find the opposite: every must contribute with a fixed amount of money. This system could increase the separate even more the different social layers. People with low resources would spend part of their net revenues in paying social taxes and that could lead them to serious difficulties to buy essential things like food or clothes. Though, that tax could be considered as a fancy payment by people with more economic power and, that way, the would become reach and reacher. Therefore, paying taxes in function of people’s salary is a more fair system which may also contribute to equilibrate the population level of life.

Once upon a time When I went to university I didn't have a driving licence, so I took the bus daily. Actually I took four buses everyday: two, to go to university, and two more to come back home. It was a great time but the truth is that I looked forward to finishing my studies. I wanted to work and have my own money. It was really tough but I finally succeeded. A few months after I finished my degree I found my first job. By that time, I already had a car thus I could drive to the office. That was not such a great time as when I was a student. Although I like to see the positive point: I learnt a lot of things and I won experience. Going back in time, there's one thing I failed when I studied: I had to learn English better. I admit it was my mistake. I didn't think it could be so useful as it is really. Now, I work and live abroad, out of my country and I'm learning a new language. So, the only advice I can give you is you to learn as much as you can!!! You never know when it can become useful.

Animals & Friendship Don’t deny it. Everyone of us have weird friends. What nobody can figure out is that some of them have hippopotamus, buffalos or lions as friends. In the Artic, these odd friendships are normally given between polar bears and dogs. The most interesting is that this type of bear, when they’re hungry, attacks dogs. But it seems there things are not what they look. The bears go everyday to play with the dogs. It is noticed, they take care of them in order not to hurt them, showing an amazing level of empathy. Anyone who has a pet doesn’t doubt it is his/her friend. But, historically, the fear to give human skills to animals has always limited the scientific thought. There is terror to embarrasment when “animal” and “friendship” have to be used in the same sentence but without quotes.

A new life in Brussels I'm a Spanish Computer Engineer. I lost my job in Spain and I was unemployed for four months. Last summer I received a phone call, a company wanted I went to Brussels for a job interview. I was very surprised because I knew my English wasn't enough good to speak every day. I did the interview and it didn't go well. However, the problem wasn't the language... was the interviewer. A couple of months later, the same company phoned me again... it had another interview for me. I went to Brussels again but this time it went really well. I was selected. Right now I'm living there (better here) and I have to speak English every day with people of different countries. I have already problems when people speak fast but I understand most of things. I found italki and I think maybe you can help me at least with grammar. I don't have much time because I'll start learning French soon, so I should improve as fast as possible. Thanks in advance and if you need a Spanish speaker... I can help you.
