Want to feel more fulfilled with life?
Do difficult things often, and on purpose.
Comfort and convenience are anomalies in Nature. Get out of your comfort zone, and only step back into it at the end of the day to rest. You are capable of so much more than you realize. You're built for it. Pushing your limits and regularly challenging yourself will fuel a cycle of self-improvement, positive feedback, and growth.
The only thing stopping you is you, and your attachment to comfort. Go out and have a productive Monday and week.
