The ability to be positive in any situation significantly contributes to being happy. I'm sure you've come across those people, who, no matter what the situation, seem to be able to find something positive about it. Everyone else around them may be moaning and grumbling, but they just manage to smile carry on. For some people this ability might come naturally, but I would think that for many people it is a learned talent.
It is hard to be positive; it is easy to be negative. It is how humans work. Take a look around you and listen to people's conversations. People constantly look for the negative, point out faults and have a downcast attitude. Being positive takes energy, and a little bit of effort.
I know myself when I'm faced with something challenging, or even something good it’s easy to be negative. At the moment I'm moving house, and whilst being in my own home for the first time is exciting, I'm struggling to think past the packing...and then the unpacking! It's just so easy to spot the negatives, the difficulties, the challenges; rather than identify and relish the positives.
So I've done some investigating this week and I came across this post at The Wellbeing Revolution about how to consistently maintain a positive state of mind. Author James McWhinney points out some key factors necessary to maintain positivity, including practicing gratitude, journaling, exercising, meditating, performing random acts of kindness and looking for something positive in every person and situation you encounter. Performing these tasks every day may take some effort, but there it is again, positivity doesn't come naturally to most of us, but I'm willing to learn and give it a go!
