One tip I can give you: Give yourself small, achievable (!) goals for each day. Nothing too fancy, nothing you need to put in hours of research before you can complete them, just something.
And then execute it. Each and every day, without failing. Sometimes you do more because you're "in the flow" on others you do the bare minimum.
I am doing this with my fitness routine for over 2 years now (started pre-COVID) and it does wonders to my brain and my overall well-being. Because I am committed. I have a streak for over two years (when I got vaccinated, I did more the days before and took a few days off - the minimum was kept for every single day, just not executed on every single day. Only exception: Vaccination) and I feel motivated not to break it.
Another tip: Don't focus on results, focus on the process.
I know it may sound esoteric, so to speak, but that helps.
Do it because you know it makes you fitter, or keeps your body at a certain fitness level, don't do it to gain a perfect body.
Look at a lot of movie stars. They train like a Berserk for a role and afterwards slack off and become fat again.
Just enjoy the warm feeling of accomplishment.
I do that with all my spare time activities and detaching myself from the result oriented (paid) work mindset has worked wonders.
Also: Motivation doesn't necessarily come before the work. For me just starting gives the motivation (so it's an equivalence or even an inverse implication of the form: Motivation follows (the start of) work

This recurrent approach worked wonders for me.
