Yes. Your description is spot on.
I will probably consider this as my first option. I loved being at that library as a student. I never liked studying with other people. In fact. I hated it. But I loved the short breaks where I could chat up people and stretch my legs whenever I felt like it. Sitting at home, this is usually limited to a trip to the bathroom.
Did you trade from wi-fi?
Internet access and having to carry with me extra screens is my biggest concern. But perhaps wi-fi is sufficient?
Yes and also at home, you are subject to lot more distractions than even if you live alone and somehow when you are isolated and too lonely, you are more susceptible to distractions than if you are in public places when there is actually activities all around you. LOL It's really weird.
Unless you can find libraries that provide network cables, you will have no choice but trade on Wi-fi and I find it adequate if you can find a library that has routers with enough bandwidth and strength. In my case, I traded on laptops and I thought that was enough. I didn't find it that practical though to carry an extra screen. To me I didn't need it and second it would be quite cumbersome to carry around plus it occupies space which would not be that welcomed by other library patrons (after all you are in public space) and third you would have to constantly have to find power plugs so you would be quite limited in where you can sit. If you need to trade with extra screens, then you might be better off trading from home. Just sit by the windows when you trade then perhaps.
Enjoy trading!
