I hate this letter $\xi$. I dont understand why we have to use this symbol. I mean there are many greek letters easier to draw. Do we use this letter in order to imply the level of difficulty in the topic it appeared?
Anyway, I always wanted to ask how to draw this letter. Should I first draw an $\epsilon$ and make a curly tail on the bottom of it, or sholud I draw an $S$ with some curly $C$ on top of it?
Could you please enlighten me about this and help me to like this letter?

$\begingroup$One way, which I don't personally use but which works all the same, is to draw a lower-case $e$ (or even $\varepsilon$ I guess) and, without taking your pen off the paper, draw a lower-case $s$ directly underneath it. It certainly doesn't say anything about the difficulty level of the topic involved.
Alternatively...
should I draw an S with some curly C on top of it?
No, it is better to draw it in one stroke. Start from the end of the little thing top left and follow continuously the curve until the little thing bottom right. Twice your pen should stop and go backwards, as is done once when drawing $\varepsilon$.

Not that I am aware of, but $\xi$ is often used to correspond to $x$, like one would use $\alpha$, $\beta$ and $\gamma$ to correspond to $a$, $b$ and $c$.

Sorry but no I could not. I find it beautiful, you do not, end of story.
