When you get on the mats it releases all the outside distractions and stresses of life. You are pushing yourself physically and mentally and growing every session (whether you realize this, or not). You will have good days and bad days, days you feel every technique is working with minimal effort, and days it seems nothing you do is right. You may tap an upper belt, you may get tapped by a lower belt, either way you will learn something about your technique and more importantly about yourself.
Leave it all on the mats, don’t brag and don’t pout, never leave the mats angry..
