You're open to the possibility that failure is going to happen and that you can't quit just because you've had a hard fall. Maybe you go the extra step and consider what to do if you do. How you'll face it. That sometimes can lead to the constant expectation of failure. If you keep expecting it and constantly go over what could happen, and don't move forward you'll screw yourself over. At least that's how I see it. One is sort of prepping yourself, honestly realizing what you're getting into. The other one was psyching yourself out. My measure?. My mother. Mi abuela too but mostly my mother. I'd say it was the whole WWJD but I'm not a fan of the hombre' I think about what she would want me to do and what she taught me. It's sometimes hard to fWhat the hell. People can just figure it out by watching that epiDoesn't make it easierRi It's easy to know but not always easy to accept and definitely not easy to do - but it helped. And it's become ... well not natural, since I still have to consciously remind myself to repeat the word, easier.
I'm not best person to give advice on emotions. I will say that letting people in will give you connections and bonds. Maybe even a chance to see why some people might do what they do. But you'll have to open yourself up. At least to them.
I don't think anyone is ever sure about that. The part people are sure about is that it needs to happen.
