how to improve my skills?

When it comes to improving a skill, any skill, 
nothing beats training consistently.

There are no magic ways to master anything. Yes, there are tips that may shorten the required time a little, and yes, the experiences of others may benefit a little, but all things become worthless without work.

Writing in al-Fusha, for example. To me it is now more natural than something I need to do a lot of effort to do. And because I can't remember what it was like when I started, I had the impression that maybe I was from the start, until I saw one of the first articles I wrote here three years ago.

As if I'm looking at someone else's writing. Yes you can still guess that I am the writer, but the style was not mature, there were a lot of grammatical errors, plus the arrangement and connection of ideas was so bad that sometimes I had difficulty understanding what I had written.

I am absolutely certain that my ego three years ago was viewing this article as a peerless piece of literature, because it was the best thing I could do. Now when I look at him with my current standards, I don't even see that I give him a passing score, which is actually a good thing. If my assessment hadn't changed in three years, that would have meant that I hadn't moved even one step further. It is more like a general rule that I use for self-assessment. If I find that I feel good at my level in a skill for a long time then I start to feel anxious, because that means I haven't changed since that time.

Of course, nothing will change without training. The only reason I've improved my writing is because I haven't quit it since, even though it was just that bad when I started. Continuity is the key to refining any skill, whether that skill is a language, a new science, a handicraft ... etc.

But the most important thing is that you have the courage to start training in the first place. Beginning is always boring and difficult, and you are sure to ask stupid questions and make funny mistakes, which is why some people may be forced to do it so that they do not look bad. These are precisely those who laugh at them. For who is a sane person who might give up something he wants to master for the sake of a group of people whose only role in his life is to mock his hard work?

You can be cowardly and look good, and you can be cheerful and make all the funny mistakes. Of these two options, there is only one that will get you there.
