Spinoza - Three important questions

When reading Will Durant's book 'The Story of Philosophy' on Baruch Spinoza,  I came across Spinoza's views on the following three questions:

1. Why should one do philosophy? (p156 - p159)
2. How can one be a good person? (p169 - p170)
3. How can one be free? (p172 - p174)

I believe these to be important philosophical questions.  Please see the relevant passages highlighted in Will Durant's book in this link.

Melbourne is currently in a 5 days' lockdown which is likely to be extended.  Perhaps Spinoza's views on these questions can shed some light on how to cope with difficult situations.
