Quitting. For most people this has a sound of failure and negativity, but in my talk i want to show why quitting is much more than this. In fact it is an essential tool for any founder, manager, engineer or poker player. I will show what makes quitting so hard and how we can mitigate the factors that let us quit too early or too late. Furthermore i will demonstrate how we can optimize our decisions if and/or when to quit at the right time. Quitting is an art. So let's practise it.
