What done is done. We can no longer dwell in the past now. But there is always time for improvements. Of course we fall, we bite dust and sometimes left for nothing. But we have a choice to either stay low or stand up, put ur hands up yell IS THAT ALL YOU GOT. REMEMBER YOUR TRAINING, REMEMBER WHY YOU ARE HERE, REMEMBER WHY YOU STARTED SPARTANS. THIS IS NOT THE END OF US. IT'S TIME TO RISE!!!
Check in day 28, things are getting weird and I feel uncomfortable. But I'm going up in this path, it was my choice the first day, and still is.
Its the change. You are changing your behaviour and your body is trying to get back to the usual one. Fight it. That's how you rewire the brain.
