You are building a mental muscle, and you need it to be strong.
I just finished writing a letter to my nephew. He is in bootcamp. I think the words here will be valuable to him, but he is not the only one. I thought I would just share a portion of my letter.
I have a feeling you like some of the things about bootcamp; and I am sure there are things you don't like. Focus on the things you do like; and just know its life. There are things I love about my career, and to have those things - I must deal with what I don't like. You are building a mental muscle, and you need it to be strong...
