On overwhelm Be careful not to overwhelm yourself with small daily tasks and habits at the cost of your ability to do the bigger projects and spend lots of time on your work in a given day. If you had all of your time to yourself every single day, you would have no excuse not to fulfill everything on your task list. However, too many days you don't live such a situation so it's difficult to hold yourself to that standard while also working on more important things. You get overwhelmed and end up doing nothing instead of tackling each task one at a time. On the other hand, most of the days when you fail to be industrious are not a matter of you being busy. You either started the day off wrong and didn't wake up early, or you got off to a bad start by refusing to work when you did get up late, or you ate too quickly—all things that contribute to your slothfulness. Let's not reduce your work to nothing just because you've had a bad couple days and failed. You don't need life to be much easier—it's already straightforward enough. The best way to tackle your overwhelm in the face of so many tasks is to be single-minded in the way you approach them. Some things on your daily task list require mere minutes from you—have intense focus for a few minutes and get them done. The earlier and quicker you can do this, the better because your mind will not waste any energy in thinking about the fact you have to do it in the first place. On larger projects that may take hours at a time, put yourself on the clock and schedule yourself to "go to work" on them. Write it on a schedule and allow yourself not to deviate from that. This hearkens to Steven Pressfield's idea of turning pro and showing up to work at creativity rather than creativity showing up to work you. These are all systems, but in the end it falls to your willingness to get to work and make something happen. Do not fall to resistance. Resist it with strength by any means possible.
On resistance 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 every day you got up early and lost the battle every time you slept in. Unfortunately, you haven't been in this warlike mindset and it might cost you valuable days of your life.
