It is important to realize that even if you get the summer cruise, it is not time to celebrate.
Your rack and stack will parlay into your next board, which most likely will be your career field.
Score bottom 50% and it will hurt you on the OML.
ROTC is like the AD world, everything will be the building block for your next goal. You can rejoice in getting it, but make sure you never take it for granted regarding your future success. Go and bust, you will feel the pain with regards to your career.
Even when you come back, you will start the vying all over again. It never ends until you stand in front of your family and friends at your retirement ceremony.
This is the marathon of your life. First out of the gate, doesn't equate to the most successful. Success occurs when you understand that every job/position/AD school/training impacts the amount of doors that will open or close based on your abilities.
I use Colin Powell as an example very often, but if you really know his path, you can easily see how he obtained the success he did in the military. He never rested on his laurels because he got XYZ, he parlayed that to get ABC. He understood, celebrate, but push forward to the next goal.
Great officers always plan 2 steps ahead. In other words, they will say I need SFT/LDAC/Cruise and GRADUATE top of the class, this will allow me to compete for my ultimate career field. Once they receive the career field, they move on and say I need to now compete for a certain school so I can be promoted. So on and so forth.
