Part of being human is that we all get sad or depressed. It's a monkey wrench in any training routine. Very quickly, you'll find yourself wanting to stay in bed, sleeping or playing video games, anything but doing the one thing you know very well could cleanse yourself of anything negative. Self improvement isn't an overnight fix nor will anyone do it for you. Only you can change you. The hardest part is taking that first step. Now I've written about this subject before and I'm sure I'll post about it again because I feel it's very important for people out there to know that you're not alone in this.
I was talking to my HTC(Hood To Coast) teammate, Mary, about this sort of thing recently over a cup of coffee. On the course or running or whatever it is you're doing, you are alone in your thoughts. No music, nothing. This allows you to think and sometimes dwell on anything and everything going on in your head at that given moment. Your mind will try and talk you out of whatever it is you're doing. This is where you can thrive and push through this barrier. Trust me, nothing feels better than overcoming said barrier and looking back at your achievement. It's such an amazing feeling. Fact is, your mind will quit before your body does.
Point to this post is that no matter what's going on in your life, keep in mind millions are going through similar if not worse situations. You have the power to overcome it, just know you're not alone. Harness that negativity and use it to your advantage. Constantly move forward, never looking back at what could have been. You can do this, trust me! That negativity is fuel to your goal of self improvement and should only make you TRI harder. Remember, NEVER GIVE UP!
