I have a nostalgic mind. When it wanders, it likes to explore the past. A style of house I’m passing may trigger memories from my student days: LAN parties and the computer games we played. Old cars will remind me of my first car, working on it with my dad. Something else may trigger memories of loved ones that are no longer with us.
The point I’m making is that my mind seems stuck on nostalgia and although it’s nice to recall memories on occasion, too much looking in the past is not healthy. You need to be looking forward to the future.
I’ve been trying to train my mind to think about the here and now or the future. It is hard though as I go for a lot of walks and practice mindfulness. My mind will wander without direction and inevitably will become nostalgic. Yet I endeavour to keep it on track looking forwards.
