I, used to spend SO much time on YouTube and Netflix. I used to binge watch videos during 5-8 hours a day, 6 days a week.
Steemit really is what helped me overcome this addiction. Now, instead of binge watching, I research for interesting topics to post on this platform. Additionally, once you realize that your bad habit is an addiction, just like drugs, alcohol and caffeine, you will be more likely to actually do something and try to break your destructive habit.
Good luck on spending your time more effectively and changing your bad habits :D
Also, thanks for the tip; I'll be centering my images next post :)
