"When you want to succeed as bad as you want to breathe, then you will be successful." - Eric Thomas
The problem with being or at least attempting to be successful comes when people try to get you down. The same goes for trying to be happy, as soon as you're happy, try to live life happily or just decide to be happy, something always happens.
I guess that's why people fear being happy. It seems like you're setting yourself up for a downfall.
Sometimes people see you being happy and they're jealous/envious of your happiness that they'll do anything in their power to destroy it. And its kinda sad too. Its sad to see someone without joy or happiness in their life for so long, that they feel you're undeserving thereof.
When you try to be happy, and do good, there's always someone or something that gets in the way.
People try to redirect you, Try to influence you to change your mind.
But what you have to do is, do your own thing, be YOU, live for YOU, dream for YOU, and make decisions for YOU. Do you want to know why? Because that's all that matters. YOu matter, and YOU deserve better.
