If you want to be a great tennis player you would buy yourself a tennis racket and spend hours practising.
If you want to be a great pianist you would find a piano and practise.
Whatever we want to achieve in life we have to put some focus or energy into it to be able to get it. The same goes if you want to be happy, or peaceful or more loving, you have to practise at being those things first before you become good at them and they become easy and a way of life.
So if you want to be happy – smile.
If you want to be peaceful – rest.
If you want to be more loving – love.
And if you want to be a good pianist go and find a piano and play it! 🙂
