Here I provides some useful links. I will not try to organise them because it is impossible. Always feel free to contact me about these links, if you find some inaccessible or you have new links. But there will only be text-focused links.

*Two* things:

- Say no to compulsive hoarding. You don’t need to collect everything before studying.
- Don’t make use of information asymmetry. Just don’t.
- I claim no credit or originality of these links
