"I admit the last couple of years shows were not up to par"

Larry Hagman's quote is most likely referring to his work in the show business. He is confessing that his efficiencies in the last couple of years have not been as successful as he would have liked. This might be due to a variety of factors, such as a lack of inspiration, an absence of imaginative inspiration, or a lack of energy. It could also be due to an absence of assistance from his peers or the industry as a whole. Whatever the factor, Hagman is acknowledging that his recent work has actually not depended on his usual standards. This is a simple and truthful admission, and it reveals that Hagman is willing to take obligation for his own shortcomings. It likewise shows that he is still striving to improve and reach his complete capacity.
