When your motivation is low, your feeling of happiness is not very high and your not in a very good mood.
Where does this come from?
It can come from a lot of places, but for it to affect you, YOU have to allow it to do so.
It’s a choice, and you are the one to make the choice. Whether you choose to be happy or you choose not to, it’s your choice.
Decide to be happy, decide what things you want in your life, decide how bad experiences will affect you, decide which good experiences YOU will create in your life and make it happen.
Look at your future, whats there, which options, and choose the options that creates a good, happy feeling for you. Focus on those outcomes and go for it.
