About Productivity System
I built this app to manage my productivity. Here, I will SHARE my productivity system and how I use the app. My system IS ALL ABOUT achieving my REAL-LIFE goals. For example: - I DO NOT care how much time I waste, - but I CARE if I read a book every day, - I CARE if I exercise every day, - I CARE if I don't forget anything, - I CARE if I constantly follow my long-term goals. Now I will show MY PERSONAL app setup with REAL-LIFE scenarios. --- Activities The first you have to do is SET UP ACTIVITIES. MY ACTIVITIES in the morning, right after I wake up look empty. During the day, I have to turn them as completed. Now I'll show how I use each activity.
