I do not consider spending my time here on the Internet is just a waste of time. Honestly, the Internet is the backbone of my life. This is where I get my income. I guess it depends on how you use the internet. If you were doing browsing without you getting benefit from it, then we can say it's just a waste of time. Even though you don't earn on the Internet, but you learn from it, then I can tell you are not wasting your time.
