I think "tuché" is too generic. Isn't better "epituchìa"?

Yes, you're right dear. "Tuche" is rather for lackiness, "epitychia" for happiness, success.
Yes, I would change the word:
τύχην--> ἐπιτυχίαν (acc.)

Thank you, Efee!

Francky, could you change?

ἡ αρχή ἡ τῶν πάντων => ἡ αρχή τῶν πάντων
I don't think there is a need for two "ἡ" before and after "ἡ αρχή ἡ" ...

In Polish language it is called "szyk przydawki" (attributive order?), This repeated "ἡ" makes the attributive important as much as the subject is.
In Eglish it probably would be: The beggining of the whole things. So, I think that tis repetition is quite justifiable here...

Please voters and translator, manage to have an agreement between you about the acceptable translation, so that I can validate, thanks a lot!

Francky, I still think that the attributive order with repeated ἡ is correct (ἡ αρχή ἡ τῶν πάντων ). This is a very often used order in Antient Greek.

I translated it into English not quite precisely. It should be rather:
The beggining - the one of the whole things.

the one --> this just beginning

The repeat places emphasis on "the beginning"(αρχή)

Repeated ἡ is correct, I agree.
