I have also learned that the military can flip you upside down and shake any plans/ temporary goals right out of your head in an instant! Here it goes for the best thing I have learned *drum roll*
There is ALWAYS a positive and a negative to anything. I have realized if I am relaxed and I take the time to find the positive in things, it will be worth it in the long run! Stress is like acid to life and people dont always realize how their negative feelings are rubbing off on the people they care the most about!
