Once you make the serious decision to be courageous enough to follow your dreams you must do your best to erase the negative thoughts from your mind. Those negative thoughts operate through fear. You may not even realize it, but those thoughts are the real reasons why you haven't pursued that one thing or those few things that you always wanted to achieve or complete. Once you start to say to yourself, "There's no way I will be able to do that, I haven't ever done anything like that before" ...you've already lost the battle. You've lost the battle because you planted seeds of doubt in the rich soil of your mind, and we all know that thoughts become things. Or in the situation of negative thinking, thoughts full of doubt don't manifest into anything but disappointment.
If you're thinking well how can I reverse my thoughts of doubt, or fear concerning uncertainty in your life you can start by immediately replacing those negative thoughts with a positive one. i.e. "I can do whatever I put my mind to, God is with me"
If you find yourself surrounded by negative sources then go be alone for a little while. It is perfectly fine to spend some time alone with God working on finding peace within yourself and instead of praying the whole time and telling God what you need try just sitting still and listening to Him with an open mind and heart. Trust me you will begin to rely upon this quiet time just to give yourself that sense of rejuvenation you need when you're overwhelmed and you feel negativity trying to creep back in your head.
Negative people can't serve a prominent purpose in your life either, you can't afford to take on the doubts and fears of another person because you have been working so hard to cultivate a garden of positive thoughts filled with hope. Eventually you have to get to a place in life where you stop listening to what everybody else is saying and listen to that one voice telling you to "Go, go ahead! I'll be with you!" Oh yeah and don't sweat the small things, once you begin to walk in your purpose and radiate positive vibes you will become a magnet for positive people and blessings don't question it just trust me that is the way it works. Still not convinced? Try it. What do you have to lose? Only a negative mindset? lol well I think it's worth a shot!
P.S. -Oprah's Super Soul Sunday was great last weekend I picked up a great quote.
