Today will be another day, which I use to write some code. That's a practice I really missed.
But let's talk about something different grievance. I am sure you have some of it against somebody?
And probably someone has a grievance against you as well.
Don't worry, that's normal.
You only need to take care that it doesn't eat you alive.
And therefore remember one thing: It's your problem that you are feeling the grievance against a person. This person probably doesn't even know or care about it.
If you are not getting rid of it, it will grow into a problem that gets harder and harder to solve.
