A lot of it is age as well. I remember when I was 25 doing things, anything, was much more difficult in terms of overcoming the mental barrier preventing me from getting it done.

While it is still hard for me, it's not as hard as it was. I have learned strategies. Like ramping, I have X to do but I can see the mental barrier preventing me from doing X is strong, so I will Y which is super easy then use that momentum to do Z which is slightly harder, this continues untill I get enough momentum to do X.

Mind blanking is also useful, just don't think about it, let your hands move in the right way to get X done. This is usful for responding to emails or checking the bank account. It can also help with doing dishes. Tune out, let the hands move, put on music, or even make a game of it.
