Today when I called in to the post office to collect a parcel, the lady behind the counter just lit up when I smiled. It was half 8 and I was customer number 23, yet I was the first person al morning who had smiled at her and treated her with positivity.The lady reciprocated and was clearly more motivated than she had been while serving other customers. It's easy to smile and be welcoming towards people, It's easy to be happy, you simply make a choice.Instead of whinging about what we don't have or all the things that are wrong with our lives, why not be grateful for all the things you do have. There is much beauty in the world yet we are all looking at Instagram and getting jealous of everyone else.Put envy aside, take a look at your life and appreciate all the amazing things that you have. Here's a little more on positive mindset from Rhiannon Roberts.... Rhiannon is ever positive and optimistic in the face of criticism and doubt. I think we can all learn a lot from the way she conducts herself. Happiness is a choice so chose to be happy. Positivity is infectious and you can start the spread of it by leading from the front.I've found myself being pretty pessimistic and miserable in the past when working a job I didn't particularly like for people I had no respect for. But looking back now I see that my attitude and feeling were my own to control, no matter how they treat me.I shouldn't have given these people the permission to make me feel low, I could have instead appreciated the good in my life, of which there is plenty to be thankful of. I'm fortunate enough to have a roof over my head, a beautiful family who loves me and my health to enjoy it.I still have my days, we all do. But when you actively try to be positive and happy, the change is remarkable. I'm a million times happier than I was, and that's through. conscious choice, not material things or more money.
