Today I am going to talk about a sensitive topic and I believe everyone areis interested in it.

No matter what kind of work unit do you work in, it is definitely a good thing to get a higher work position, but the attitude towards this thing is very different forom each person.

First, I will give thosem who have made a great progress in their position promotion a big congratulations.

this is the result of their hard working, and a recognition from their leaders.

But Iif you didn't get an ideal work position yet, please take it easy, don't be upset about it.

No matter what kind of work do you do, what position are youyou are in, that doesn't matter, just do it well, so we can feel peaceful and solid.

I am not sure what you meant by "solid".

If you are kind of interested in posiromotion, just strugglework hard for it, and If you wearen't, just be yourself, that is such a simple thing.

I am very satisfied with my position, though it is notI haven't been promoted forin over twenty years.

Many of my former colleagues work hard, and also have comprehensive ability as well as a high level, but they haven't got a position as high as mine, however, they still work hard, never complain.

As tofor me, I think my ability just suit fors a small team leader, even not suitable enough for a class monitor.

Of course, there are also many colleagues theyat have got a high position than me, that is just because of their hard working and their strong ability.

This is my opinion about the topic, and I don't know Iif I make it clear/if I made myself clear.

Today I am going to talk about a sensitive topic and I believe everyone areis interested in it.

I would suggest also the use of the conditional here:

Or a future tense:

Today I am going to talk about a sensitive topic and I believe everyone will be interested in it.

Please take it easy isn't the phrase you are looking for. It means more to reduce effort, or to relax.
