Keeping my Mind Sharp in Retirement

Eight months into retirement, I'm settling into a good routine and pace of life. Keeping both my mind and body sharp is key. Here’s how I keep my mind engaged:

For me, keeping my mind sharp means staying mentally active and challenging myself in different ways. These areas often overlap.

I stay active mentally:

I actively read.

I vary genres to make reading interesting and challenging. For example, I’m reading Gardens of the Moon by Steven Erikson, an epic fantasy novel that's new to me. I’m also reading Ryan Holiday’s Wisdom Take Work and Sketching in the City by Toby Haseler.
I try to vary the genres to challenge myself and to have a different, new experience while I read. Currently, I'm reading Gardens of the Moon by Steven Erikson, which is described as an epic fantasy. Something different for me.
To build the reading habit, I set a low daily goal of reading just two pages. It’s easy to achieve and helps me read more without pressure.
I keep each book with a pocket notebook for ideas, concepts, and new words to look up.
Right now, they are all three physical books, but I also use a Kobo to read. Typically, I read Fiction on the Kobo and keep a small notebook for quotes or thoughts.
To keep the habit easy, I set a low reading goal of only two pages a day. This makes it easy to start, and I usually end up reading more once I get going. 

I challenge myself mentally:

Developing a Robot in Claude Cowork.

To challenge myself, I’m learning to create a robot using Claude Cowork. The process of building markdown files and programming tasks keeps my mind engaged and reminds me of building Excel macros in my working days.
The robot now handles routine tasks, tracks my plans, and challenges how I manage projects. I always review its suggestions myself.
I have the robot doing routine tasks that used to take me a fair bit of time, and it also helps me keep track of tasks and my plans, and challenges me on what I'm working on.
I never let the robot decide; it just presents options to me.
Learning Claude Cowork and finding robot tasks reminds me of building Excel macros during my working days.

Creating art daily.

Creating art daily is enjoyable because I focus on the process rather than the outcome. My aim is to simplify complex subjects and express my interpretation, not pursue realism.

I fed it all the books I have, the courses I own, and some of the key artists I follow on YouTube, and it presented a first-pass daily art curriculum. It's a first pass, and I modified it to work exactly for me, but it gave me prompts and skills to think about building.

I started making art just a few years ago and have enjoyed it deeply ever since. It’s an activity you can begin at any age. I stay clear about what I want to achieve, and I measure my progress against my own goals rather than others’ work. 

The key to a sharp mind is to choose activities that challenge you, keep you active, and encourage ongoing learning and growth.
I just started this a few years ago and really enjoy it. Something that you can pick up at any age. I'm clear about what I want to get out of it, and I'm intentional about it. That way, I compare what I've done against what I wanted to achieve, not other artists. 

The keys to a sharp mind are to intentionally challenge it, keep it active, and continue learning and growing.
