He told his grandson that violence is more than fighting, beating, killing & wars.
Made him split what he did into "Physcial" and "Passive". With a tree structure. Kept it up to date each day. Passive violence leads to psychical violence.

| Was not a product manager, read about Scrum & product management in it. | |
| Scrum says: work out what to build, prioritize & estimate, give feedback shows | |
| Other: Competiive analysis, pricing | |
| No longer a product manager | |
| It's super easy. Once you have an idea, you can get loads of stories. (priortized and esitmated, then actually build it). | |
| Came up with a product over 6 months, got 2 months feedback. Next two years a blur. |
