Fellow devs,

If your boss asks you for an estimation don't follow your gut coz your gut sucks. Ask for time to analyse before giving any estimation. And yeah don't forget external factors such as :
- third party tool down (github I'm looking at you)
- updates (windows, IDE, etc.)
- 90% of the time it doesn't work
- if it involves front dev just go ahead and double your estimation
- YOUR BOSS THINKS YOU OVERESTIMATED

Sincerly.
