It’d be better, particularly in Friendly, to avoid sounding like an authority, especially when giving advice. Make it easy for people to make their own judgments and maybe not listen. And try not to pressure people.
For example:
you should read the entire article, slowly and carefully.
Is telling someone what to do. Instead, it’d be better to say that you think doing that could be helpful/useful and why.
Similarly, this statement is pressuring:
If you try to avoid them then you will never master them.
It suggests that if someone doesn’t take your advice, then their problem will never be solved. And the next sentence amplifies the pressure:
If you want [good thing], then you need to [do what I said]
It’s like the “should” but stronger (“need”) and also is using a negative outcome to push the person to comply.
Another part I noticed is:
the best chance
Saying “best” is a very strong word. It’s like using “all” or “never”. It means not merely good, not even great, but #1 in the rankings above all others. That claim is unnecessary and doubtful, and it’s also adds pressure because who wants to reject the best thing? Changing it to “a good chance” could get across the same main point without the same problems.
The post also has a time pressure element:
the further in the past it gets
There was a topical reason for saying that, but it’s also problematic because it increases pressure. It might be OK alone but it amplifies the other pressuring elements.
