Wheels.

You know why being around negative people is so tiring? It's simple, it's so simple that it's just basic mathematics. You have a certain amount of energy. They have negative energy. Sum them both and you'll lose your energy. It's as simple as that. Being in a positive zone will have the opposite effect because again, it's simple mathematics. Your energy will get replenished because people exuberate positive energy. People radiate positivity and you absorb it. You feel motivated and energised when you absorb it and you will feel the need to get things done, to get things sorted out, to get things accomplished. That's why you need to be positive, and be around positivity. You can't always spend time with people who suck your energy out, you can't always be around people who make you feel unmotivated because you have goals to achieve, dreams to turn into reality, remember? You're special, don't believe anything else. Get working! No matter what your goals are in life, they're not unachievable. Get the wheels rolling! 

Love, peace!
