Have you paid attention to how the optimistic people speak?

Do they indulge or do they refrain from using low energy words like sad / anxious / depressed / chaos / hurt / teach someone a lesson / etc ?

Do they indulge or refrain from topics that are divisive (criticising decisions AFTER they have been taken) because they know the stressful effects it has on their emotional make up?

Do they indulge or refrain from unnecessary drama, malicious gossip, and psychological warfare?

Just observe optimistic people and you will learn how to be optimistic.

Just observe friendly people and you will learn how to be friendly.

Just observe people who have the qualities you desire to have and you will know how to have them too.

Do not struggle to be who you want to be. Observe. Learn. BECOME.

Its that simple. It has always worked for me.
