Suomi48, let me interject the casual conversation with a more serious, but potentially helpful, Sunday message.
If you were younger, your lack of interest and motivation might be attributed to depression. But given your age, I'd attribute such feelings to a lack of purpose with one's life. Let me explain a bit.
I spent most of my adult life being focused on my career, and since I didn't raise a family like others, I directed my free time and attention to outdoor sports, trips, and adventures that kept life busy, fun, and interesting. An aging body and forced retirement changed that though, and for the past 5 years I've had to turn the focus of my life to other things. In short, I've had to find a new purpose for my life.
Now, I've always been a Christian, but faith was just one part of my multi-faceted life. Since retirement though, I've redirected much of my free time to putting faith at the center of my life. There's been many ways of doing this which I'd be glad to share with you or anyone, but the important point is that it's given me a purpose for my remaining time here and a genuine passion for things that matter. And the more I learn, the more I appreciate the free time I have each day to make it count.
I used to love my job, my trips, and my high adventure outdoor sports. I thank God for the extraordinary life he gave me, but my low key life now is actually fulfilled with more meaning and passion because I'm focused on what we were created for - to know and love God and to love others. Life is about relationships, and being busy with work, hobbies, or the pursuit of other pleasures won't bring genuine satisfaction for most people - and won't bring lasting peace and joy for anyone.
Listening to music, collecting stamps, writing poetry, and playing with trains are all good activities in my view. But for a worthwhile passion? I'd suggest you focus each day on knowing and loving your Creator more. There's so much fascinating material to read, watch, and listen to. So many Christian related political issues to care about. So many people needing help and guidance. When you direct your time and attention to the most important things in life, it's hard not to develop interest and passion. Let me know if I can help in any way.
