All things have ends. Nothing lasts
If I am currently sad, this situation will pass.
If I am currently happy, this situation will pass too.

If there is a bug, boss like shit.. it'll pass, it doesn't deserve to be that sad ans depressed..

If there is no bug, and the work is perfect.. it'll pass.. there will be moments when sadness come..

it's just everything is going, nothing deserves to be sad or that happy.
