Perhaps part of your problem with being lazy has been your lack of naming the enemy. You used to get up super early in the morning because the enemy, Resistance, told you not to. You overcame that enemy with each day you got up early and lost the battle each time you slept in. Unfortunately, you haven’t been in this warlike mindset lately, and it might cost you valuable days of your life.
*This is another idea from Steven Pressfield’s The War of Art. If you haven’t read this book, you need to.
