Are you a glass half empty or a glass half full type of person?
A US study revealed that optimists are more likely to live longer than those who have a more negative look on life.
The theory goes that optimists may find it easier to control their emotions which protects them from the adverse effects of stress.
Researchers in the US also suggested that pessimists could benefit if they thought about a future where everything turns out well.
We have been finding out how some of you stay positive and what tips you might have for pessimists.
'Don't linger on negativity'
The expression "the grass is always greener on the other side" does not necessarily ring true for Tania Guarda, from Lisbon in Portugal.
"Everyone has problems. I try to enjoy and love my life for what it is. I truly cherish what I've got – good health, family, a loving partner and a job I enjoy."
To avoid anxiety, Tania tries to imagine herself sorting out her problems and focusing on how she will feel afterwards.
She also does not linger on the negativity of others, adding: "I don't let negative personal comments get to me."
'A sense of humour'
Vicki Siska, from Colorado, has been through some stressful times but has managed to remain optimistic.
"Music feeds my soul, a sense of humour keeps things in perspective, and I have good friends who love and care for me," she said.
Humour also helped Pippa Kennedy, from Hertfordshire, stay positive. She watched box sets of the BBC TV series Dad's Army to help her get through a bad break-up.
"I also think being grateful for what you have – and lots of chocolate – helps," she added.
