I would like to say "A gradually will become B while you keep doing C" using "as" like this:
As I use it for a long time, it gradually becomes a treasure for me.
But I feel "as" requires a situation in which something gradually changes explained right after the word if a situation explained after comma also gradually changes. For example:
As it got darker, the winds blew stronger.
Could you please tell me how I can express the first sentence properly?
The word "as" is not at all limited to "a situation in which something gradually changes". It can also reer to a very sudden event
- The great tree made a stunning sound as it struck the ground after it was chopped at the base.
- The illumination shell turned night to day as it exploded.
- Everyone present felt pity for Jane as she suffered a sudden seizure.
- The crowd let out a gasp as the Senator announced his change of party.
"as" (in this sense) simply means "while" or "at the same time"/ It often, but not always, suggests some relation of cause between two things, but not always:
- As Fred grew older, he became more politically conservative.
- As Jane became more settled into her job, she developed a fondness for coffee.
As I use it for a long time, it gradually becomes a treasure for me.
is as perfectly valid sentence. But so would
After I had used it only twice, it had already become a treasure for me.
