How to tactfully negotiate your salary

Over the years I had many friends ask me for tips on negotiating their salary. I always though this was a very dense guide which brings up to speed starting from 0. Recently a friend was negotiating an offer (he ended up increasing it by more than 50%), and I thought there might be many people which are not familiar with this topic. Spending 1h on salary negotiation is going to be the best ROI you'll ever get in your career! Disclaimer: I'm not affiliated with the site, just a happy user)
