“Life is most risky when it is sweetest. That is when you can blow it.” (Romilia Quotes)
This is true. You are careful with your life when life is not easy; when you lack the means to live an easy life.
But when you have the means to live an easy life, it becomes very easy to derail; to think you can do whatever you like; and you start venturing into things that can destroy you.
At all times you should be level headed and more especially when life is going well for you.
It is a sign of both wisdom and maturity.
Do not blow it! You may blow your life.
