"Embrace the suck" is a big one for me. I work outdoors and unless the weather is dangerous you still have to get it done. So when proper shit weather hits I just laugh now because while its going to be terrible its going to be an experience.
Like that time I did 10 hours in 40c heat during a dust storm, wearing a respirator. Worst day ever... hell of an experience though.
I honestly read this and until I saw the comments I assumed they were gaming and she locked in league champ select which is a valid time to cry seeing as youre about to play league.
I however cry quite easily. In hindsight all this "don't suppress your feelings" advice honestly always felt more directed at boys and men.
Learning to turn off and distract yourself from bad feelings is also a skill. I think quite a few people - especially women - struggle with that, me included.
Traditionally, to be "locked in" on something would mean to be locked in on your target, goal, etc.
Telling someone to lock in or "lock it in" is kind of like a nice way of saying "get your shit together" or "focus up". I hear it in sports/ gaming lingo.
After all the stories about how male authors can't do realistic female characters, someone reversed it and asked how could you instantly tell if it was a woman describing a man.
The book 'The Outsiders' is about a bunch of tough guys who spend a lot of time talking about their feelings.
