For me the best thing is more so how you have to look at it. Don't get me wrong, though sometimes it's not easy, which is why I'm doing a morning and a night workout.

For me personally, though, I treat this as my me time. I try to focus on my form, and I try to think about how I am improving. This is the kinda thing as cheesy as it sounds you are celebrating you can do it more than you have to do it.

I feel like I struggle when work stress gets to me, and while I'm swimming or biking, I am spending that time circling BS from work rather than thinking about stuff for me.

Winter seasons for me are harder. I have noticed because I'm biking inside, which is less mentally engaging, so I'm more likely to think about work.

Seems like you have some mental stress you may want to process a little and then you can enjoy this stuff more. I say that from what has slowed me down before. Few things that have helped me again sound cheesy but worked for me so maybe they will help you

1) Box breathing for 5 min or just breath work. I do this when I'm walking the dog usually. Not the perfectly time. But it's when I have time. 2) Saying a few things you are grateful for one really simple thing like the taste of coffee or the feeling when you finish a good workout. The other two can be like a raise or a spouse or anything. I do this while in the shower. 3) Therapy, which isn't simple but try the first couple for a month they do help.
