My final decision

“I took my final decision!”
“I will improve!”
“I will show you from tomorrow”
I said all of these sentences several times but did I do
them?! It’s pretty clear. But this time is different {I
heard this one also before!} C’mon this time is really
different, I will not show you from tomorrow. I will
show you from now on. {I have no idea!} I will say
NO to those things which waste my time.
