Freelancer Guide - Tips & Tricks - HITMAN World of Assassination

I know I'm late with this kind of video. I had this idea for a long time and I finally made it.
This guide has a lot of basic freelancer tips and tricks and I think it can help people who are starting freelancer mode and are struggling with completing campaign.
Guide is not exhaustive. I included only what I considered important and worth mentioning.

Useful links:
https://www.hitmaps.com/ - extremely helpful interactive maps with locations of everything everywhere in Hitman.
https://docs.google.com/spreadsheets/... - spreadsheet mentioned in the video. Contains list of the items and their locations, that you can bring to safehouse from the mission. I don't know who is author of the table, I'd credit if I knew.
