Stop Carrying Your Baggage
There's no need to do the same things you did yesterday. The same complaining. The same whining. The same poor habits. The same (insert here).
If a farmer refuses to till the soil, there's a high probability that the result will be an unhealthy crop.
So, shift your behavior. Change what you're doing in order to possess a healthy mindset.
Stop carring yesterday's baggage. If you carry your baggage, you will always be tired. Change your thoughts.
