“True happiness is to enjoy the present... not to amuse ourselves with either  hopes or fears but to rest satisfied with what we have, which is sufficient, for he  that is so wants nothing.”

— Seneca 

We’ve all heard the age-old advice that living in the moment is the  secret to happiness. But anxiety about the future isn’t the only thing that  keeps us from staying grounded in the present. You should beware of  nostalgia, too.  

Nostalgia is usually harmless, and it’s fine to let yourself smile at happy  thoughts of the past occasionally. But that easily turns into sentimental  longing, which feeds stuff like depression, self-pity and ungratefulness.  

Nostalgia is a bit like alcohol — a drink or two is fine, but once you  start it’s easy to overindulge. What’s pleasant in small amounts can quickly  lead to suffering.  

The “tipping point” for nostalgia comes when you start comparing your  happiest memories to what you’re experiencing in the present. If you’re  indulging in nostalgia, be careful not to fall into the trap of thinking “today  must be bad, because yesterday was better.”  

Don’t be sad that a good experience is over. Instead, be grateful that it  happened... and then choose to go and have more good experiences. 

Cheers
