personal agency and the choice around how to behave - and for many it is a choice
I agree that it is a choice, but again, the very idea of having a choice around how to behave is being eroded by society in general. The virtue of self-control is now almost non-existent - what is lauded instead is letting it all hang out, creating drama, giving way to your emotions, being 'true to yourself'.
Every time someone weeps and wails on a talent show, every time someone has an "OMG" reaction to a minor incident on social media, every time someone posts an inspirational meme about 'living your best life', every time someone throws a tantrum and is rewarded with 'R U OK?' - somewhere, a piece of someone's self-control crumbles away.
Extol the virtues of 'keeping a stiff upper lip' in 2020 and you'll be laughed at, or accused of bottling up your feelings, being emotionally stunted etc. Yet, that's what we need to learn to do - to control ourselves and not give in to every impulse as it occurs.
Want something? You don't have to save for it - buy now, pay later. In other words, reach out and grab whatever you think you want at the time.
Yes, people can ignore the tide of useless emotions washing over us every day, and the chorus of media voices telling us to reach out now for whatever we want in life, but it takes a strength of character that not everyone has.
