It may feel strange to be early at a meeting, even awkward if you don't know what to do while you wait.
|Running after time adds negative stress and makes you more likely to be always late|
However finishing a meeting early is a great thing. It'll create time for others things you didn't think you could do. People will even envy you for being able to close things on time.
Being early starts in small things, like being early at a meeting to make sure it finishes early. It'll open up new opportunities.
