Does player really think all of the time about special opener ?

It really wears me down to try to come up with openers.
Sometime it comes to me like observation/context.
But places that aren’t for socialization like gym or beach are really difficult.
Plus I feel awkward doing all the pick up lines or observation on a women.
Like at the beach coming up to two girls tanning and telling them to put the headphones down and saying directly to them it so hot that I don’t understand how people can tan.
Or at the gym coming to them telling them to put the headphones down and saying is your playlist that bad or you super focused?

P.s just approached a girl telling her in Hebrew”hi you seemed interesting” waiting for her response”I have boyfriend” “okay have a good day”
I held eye contact but my voice always betray me.
