English speaking - some useful pharses to speak fluently

Luck starts with happiness

What’s the best way to be a happy-go-lucky person?

Stop, look and listen: Take time each day to absorb the details of
your surroundings. Notice the colours, designs and patterns of nature
and architecture. This will heighten your sense of beauty and make
you feel good.

Realise things could be worse: Make a point to be thankful when
good things happen to you. Don’t think too much on bad things but
focus on taking steps to improve your life.

Feel the bliss: Think about how you feel, as you are experiencing
what you enjoy most in life. Let your experience fully satisfy you and
pump up your happiness.
