I want to be an actor but my acting skills aren't that great is there any sloka/strota/prayer which can help me with it
Practice makes a man perfect. Do it till you are perfect. There is no shortcut for hard work.
कर्मण्येवाधिकारस्ते मा फलेषु कदाचन । मा कर्मफलहेतुर्भूर्मा ते सङ्गोऽस्त्वकर्मणि ॥ ४७ ॥
You have only right to your actions, never to the fruits (of the action). Let not the fruits of action be thy motive, nor let thy attachment be to inaction (Akarman).
Best of Luck. 👍..
