As we age, we end up becoming more connected to ourselves: likes, dislikes, and many other beliefs become de facto. We tend to focus on what really matters to us more than what others will think.
Our bullshit detection keeps on improving, and we become wiser in staying away from what we don’t want. This inner self tends to make us calmer within. We are least bothered about externalities and tend to focus on the internal. The glamour, consumerism, and all other distractions end up taking a back seat.
The closer we are to self, the more we have time for ourselves. As a result, we can spend time on rebuilding ourselves: our hobbies, unfinished readings, and writings.
In earlier days, we would call it retirement. With Capitalism taking the hot seat, the retirement concept has gone alien.
