If you are surrounded by problems and cannot stop thinking about the past,try to focus on the present moment。Many of us are weighed down by the past or anxious about the future。You may feel guilt over your past,but you are poisoning the present with the things and circumstances you cannot change。Value the present moment and remember how fortunate you are to be alive。Enjoy the beauty of the world around and keep the eyes open to see the possibilities before you。Happiness is not a point of future and not a moment from the past,but a mindset that can be designed into the present。
