Work life balance - Tips

I work in a startup, have been since the past 4 years. Earlier it was WFH, I had the liberty to work whenever I want - task had to be done.

With experience, I've felt that my work life balance has gone for a toss. I'm not sure what I'm doing wrong, I feel exhaused and burnt out. This is also sucking out ownership from what I do.

To all the GVs out here, have you guys tried doing something that's helped you? Or are we all on the same boat here? Are folks in MNCs going through the same? Genuinely seeking for help here.

I just feel ki, I should stop running behind money now. Take a pay cut if needed and join a company thats a bit more established.

Ps: In my case working from office seems like a total waste of time. I had been so much more productive at home.

Thanks!
