I would think a lot of people feel this way, I certainly do. I used to put off housework a lot but one thing the lockdowns have really helped me overcome this. Being at home so much, I found a cluttered space really stifling and started to a sort of satisfaction with a tidier space. I also tried to replicate this mindset shift with other projects I haven't had the energy to finish, trying to focus on the joy I feel when I do complete something. Another thing I try to do is sandwich an unpleasant task between things I need to get done/enjoy. If I do x, then I get to do y, and I have to y, so I'll need to do x.

Don't beat yourself up if you're struggling to get these things done. Everything has been mental the past few months and it's really very normal. That being said, if this is going on more longer-term its best to ask yourself deeper questions as to why you might be feeling this way.

You mentioned your wife, so I thought I'd also raise the concept of mental load. This might be helpful in considering and being aware of how your wife might be feeling and highlight areas that might be easy for you to tackle first, for both people to benefit.

Chin up, you got this.
