Why making a ‘reverse bucket list' can help you feel happier right away, according to a psychiatrist

The useful part

When it comes to being happier, we often look to the future — what we can change about our lives, our relationships and our upcoming contributions. In fact, if your goal is to be more optimistic, Varma said, one fundamental approach is practicing gratitude for the life events that have already occurred. Create a 'reverse bucket list' To boost your mood, create a reverse bucket list, where, rather than focusing on the experiences you hope will come your way, you look back on moments passed.

How it works

• Perhaps you didn't take the time to bask in the joy or sense of accomplishment the moment deserved — it's never too late, said Varma.
• "So many of us have these future forward-facing bucket lists of, 'Oh, these are all the things I want to do,' which is great," she said.
• What a reverse bucket list does is say, 'Look at what I've already accomplished in my life.' What are the things that I'm grateful for?

Details worth keeping

It's worth reflecting on the moments that have already passed, too, Dr. Sue Varma, psychiatrist and author of "Practical Optimism," said on TODAY.
