Whether you like it or not, no matter how productive or efficient you think you are, there is no way you can complete everything you want to complete.
A truth I've learned the hard way
It is true that in life everything is limited whether you like it or not, I think the most important thing is what you want in this life and to keep it at all costs.
I for one will live believing what is right FOR ME and not what a religion says or the neighbor who smells like pee or what people say is right in society.
That would be life
