What is the best way to become a better writer?

Write.

I know writing is not always easy.

I have found the best remedy for this is to make a commitment to write.

Before making a commitment, I found myself unable to write for one reason or another.

Any excuse would do. It was Monday. It was Friday. It was the weekend. It was a holiday. Any excuse would do.

It was only when I made a commitment to write every day, that my writing started to improve.
