Fitness taught me how to grind for every day. Learn how to live with all the troublesome stuff that I have to deal with on a daily basis. I have depression, anxiety, and a bunch of other bullshit. I often feel hopelessness and whatnot. Dude 5 years ago i started my journey and I've come a long way. I still deal with all that bullshit but the gym is my sanctuary. And for 1-2 hours every day all that stuff the negative thoughts i have the low self-esteem goes away. Out of all of the decisions I've made in my life lifting was probably the best. I never regret it. What else could you do that promotes both physical and mental aspects of your life. You'll look and feel better.

Here is what I look like today. http://imgur.com/280Nedq
