Summer is a feeling, a state of mind. We bet you already know how it feels. Summer is what it feels to fully cross off a list, when a self shining idea arises, when everything goes well. Summer is setting the auto response for 15 days and feeling everything is under control. It is the first beer after work, the warm sun on the face, the goosebumps, exceeding the KPI's. Summer is that 
specific time whan things happen, when ideas meet people.
