The joy of bling! Sparkles may sound rather odd as a helpful tool, but to me they are very important. I think it has to do with the way the light refracts and sends bright rays shooting out as you watch.
On a grey and depressing day wearing a sparkly ring or bracelet always lifts my mood. There’s no need to spend a fortune as long as it shines brightly. (My favourite helpful ring cost just £1, see picture). Watching the play of light for a few moments is soothing, inspiring and almost meditational. Such a simple, pleasurable tool.
Sparkles on clothing and shoes are also very cheering. As are sparkly items around the house. Bring out the bling! You may be surprised how much better it makes you feel. Give it a go.
