When I was little I was unsure about everything and fretted about anything. If the cat was sick. If my teacher wasn't on form. If my parents were unhappy. Sometimes I would come away from talking to someone who was negatively charged and feel inexplicably down. They would say something slightly critical and I would feel annihilated.
In the 21st Century we can live such busy lives that it's very easy to lose awareness of the ability we all have to control our emotions, our state of mind and the skill of planning for happiness. Rather than just letting life happen to you, how much better might it be to consciously steer it, through your actions, thought and feelings, in a more positive direction?
When I was a student I thought cannabis was a harmless pastime, no worse than alcohol, and I was encouraged by the fact that it's not addictive. Many years later I ended up working for an addiction rehab clinic in Scotland where I found out that not only is cannabis addictive but the skunk version of the drug is known to send as many as 20% of users into a psychotic state.
