You have better self-control than me.
This is the ultimate problem. It's a human issue, not a technology issue.
Here is an example from my life. I enjoy cannabis. I love the creative mode I get into when I use it, I love how periodic use can allow me to reexamine things from a different perspective, and so on. Great stuff. (and yes, it is legal here and sold in about 4 stores within a ten minute walk)
What I don't like is how, if I have it sitting around my house, I am tempted to use it when I need to get work done, and it will get in the way of that and cause me to waste time. I would become an unproductive stoner if it was always around.
Enter technology. I bought a lockbox with a timer. Pull out a little bit, then lock it up for 4-5 days. Works perfectly for me.
Some people could say "why not just learn some discipline?" (easier said than done) Others will say "if you have an addiction, just don't buy the stuff."
I say, why can't I have the best of both?
Same goes for things like phone and web addiction. Technology can help. I don't like this solution (too all-or-nothing.... it's like the "just don't buy the stuff" solution), but I do like the idea of technology helping with what is otherwise a human issue.
