Change a Little Bit

I thought those days in the past were boring!
From that time then, I started to change them. I wake up early then cook breakfast for myself and my family.
I walk to the nearest market instead of riding the scooter.
I practice the Ukulele in the morning and sing some songs_and so on.
I've done those for over one month, and I feel much happier.
From now on, change a little bit in your daily life.
Live the life you imagine!

Although "from that time" is grammatically correct, we almost always will say "since then," or occasionally "from then."
