You have to do some self analysis today. Ask yourself "Am I thriving or just surviving?"
Are you going through the motions or going all out in everything you do? Are you just maintaining your weight/fitness level/strength?
Every day is your chance to get better, are you taking advantage of it? Even if it is just 1 ounce lost/one more step on a run/one more pushup that is progress and that is what you are looking for. You didn't progress, why not? Didn't get to bed on time, don't feel good,tough day at work, etc. Doesn't matter, you gotta make it happen.
There's an old saying about excuses. Something about everyone having one, maybe you've heard it. Everyone has a reason to quit, a reason to not go on. What separates the successful from the unsuccessful is what they do when things aren't all hunky dory. Yes I just used hunky dory.
So if you're just surviving, it is time to take it to the next level and start thriving.
