In which tense are you living in now?
It’s ultimately your choice, so do ‘YOU’ need to make a change to ‘YOUR’ life?
Lao Tzu is a particular favorite of mine and I have studied his writings but he is only one of many great sages that can offer you great advice and help you bring your thoughts into the NOW.
The Now is where you need to be, you need to be happy and content with who you are and where your life is taking you, if not then you need to make a change.
I wish you happiness, love and peace.
