@Omrrc I can totally agree but I'd add that for me it's also the fact that going out adds stronger purpose, intention and, ironically, fewer options or choices. So it makes the activity more purposeful and clearer for me.
@ChrisJWilson it’s good point that. Ironically, or at least it feels so, when my wife goes away and it’s just me and the kids. In those situations I find it easier because as you say I’m more focused when it’s just me!
