Pessimism is for losers. It’s a total disaster for your mind and your life, believe me. You cannot afford to be negative, not even for a single second. When you sit around whining and complaining, you are just bleeding energy and looking incredibly weak.
Look around you. You woke up today, didn't you? That is a total miracle right there, but most people are too blind to see it. Being alive is absolutely fascinating, it's incredible, but you have to actually open your eyes and appreciate everything. Stop talking about other people, stop the pathetic gossip, and stop wasting your time.
You need to do what you love most and you need to make things real immediately. No excuses. Be enthusiastic, bring massive energy to everything you do, and stay viciously optimistic no matter what. Anything else is just complete and total madness.
