Today is the first day of the rest of your life

One day, as usual, I was watching the drama.
Then my favorite one is "Breaking Bad", which is one of the most popular all over the world.
The story is kind of about drugs, the high school teacher started to refine drugs as a side business.
Meanwhile, suddenly I was shocked by the serif enough to take the screenshot.
Today is the first day of the rest of your life.
It's the truth and natural but this sentence is unforgettable all the time.
Life is short to make something done, though it should not be explanation not to do.
I have studied English since I was a middle school student, it's about 10 years. but I cannot speak less than I expected before. this gives me strong regret and encourages a determination to study abroad.
I have many chance to regret in my life. but I want to live to recall the phrase sometimes without regrets.
And I always cheer up like you trying something.
