What does that mean? Don't get complacent.
We've all been there. You see the lowest weight on the scale you've seen in months then you decide to "slack off" because you've rationalised you're already at your goal because progress... Right? Wrong.
People say a loss can make or break a fighter, but a win can also make or break a fighter because they get comfortable with a win and slack off.
Discipline is what will keep you on track through ups, downs, lows and highs. Discipline is waking up and doing what you have to do irrespective of your mood, environmental factors or anything else.
The solution is to keep an objective, level-headed and disciplined approach to your training -- and your life.
