An article translated into Russian confirmed that Allah's blessing of making seasons for righteous deeds to increase our good deeds. The blessed one is who takes advantages of them. One of these seasons is the first 10 days of Dhul-Hijja that the Prophet (pbuh) confirmed they are the best days ever so he encouraged us to do good deeds. Moreover, Allah, the Almighty, swore in these days which illustrates their importance, for Allah, the greatest, does not swear by anything but the great.
