A wrong decision made is better than an opportunity lost
While you are second guessing yourself, the door of opportunity is open for everyone. Make a decision, grab the opportunity, a wrong decision made is better than an opportunity lost. A wrong decision made will always bring a positive lesson - an opportunity missed will always bring the same lesson: I should have made a move on it.
Every person who has ever succeeded made many wrong decisions and took the lesson from every decision and used it to propel them forward. Why would you think that you should do it perfectly on the first attempt?
Make that decision to follow your passion. Take a leap. Appreciate the lesson. Apply the new knowledge and take one small step every day. Tomorrow, next week or next year you will know that you have won with every small step.
Are you ready?
