Realizing that everyone is abstracting their own reality, none more/less true than your own. How they interperet things is no less right/wrong than yours, since you'll never be in their shoes and be able to observe that. It makes all the things you find abrasive about others less significant, and instills humility upon judgement of others and their actions.
Do onto others as they do unto you, judge lest not ye be judged.
Everything is relative, the razor's edge is balance. Observe and consider your actions with more effort than the actions themselves.
Insanity is far easier to see in others than ourseleves.
Belief is a tool, not a disease. It can be used productively, or abused.
Balance, is the key to happiness. Stray too far into focus on one thing/idea/effort and neglect the infinite possibility life provides, and you will regret the decision.
What seperates insanity from genius is the ability to use that energy both have in common productively. One lacks dicipline and perspective, the other recognizes it as the most important factors to consider in all lifes challenges.
Take time to apprecciate what you have, and never forget theres someone out there who has is much worse than you. Always be open to help those who are less fortunate than you, because if you were walking around in their shoes and vice versa, they would gladly do the same for you.
Don't get caught up on making sense of everything. It only leads to insanity. Life is chaotic.
