Are you challenging yourself every day, or are you coasting through life on "Easy"? From what I've found, most don't challenge themselves on a daily basis; coasting through each day tends to be the norm. We all know that getting outside of our comfort zone is where true progress is made, so are most not doing it?
Challenge yourself today to get outside of your comfort zone in one of these capacities today: Mentally, physically, emotionally, or spiritually. It doesn't have to be much, but a little bit every day over the course of time will go a long way over the course of your life.
Small victories on a daily basis will go a long way towards boosting your confidence, ability, positively impacting your mindset, and allowing you to take on bigger challenges daily that will result in bigger accomplishments, however they express themselves.
Earn it. Everyday.
