Ralph Martson, once said "Just imagine the incredible power of being able to say "I can" when everyone else is saying I can't.'"
How true is this? Have you felt a whole new world opening for you the moment you "I can". Your confidence with soar high your spirits, your mind will explore the uninitiated and you'll have plethora of options before your eyes to take your pick on how you want to deal with the challenge or task.
CONFIDENCE SELLS and it has amazing contagious power. People believe in those who believe in themselves. No one wants to be stuck in a room with other people who feel like they don't deserve to be there. Stop wondering if you're good enough. Know you are, and behave accordingly. Put in your best always. Pluck out the weeds from your road to achievement and pause, assimilate before taking critical decisions. Rushing into any situation is highly detrimental, so avoid it as much as you can. It will be an exacting sojourn but when you see the desired outcome, you will feel exalted and overwhelmed yourself and say "It's been worth it". Sometimes things don't work out as desired but you'll surely learn from the experience and wait for the next opportunity to be grabbed.
"I can't" is a classic quitter’s syndrome. Before they happen to influence you, put them in the IGNORE mode and move on. It saves a lot of headache and wastage of time that could well be invested elsewhere. This is also an indicator that it is time to change people around you.
As Ayn Rand says, "the question isn't who is going to let me; it's who is going to stop me."
So, what's stopping you, eh..?! Get going...
