There is a very powerful idea that lives in the souls and the minds of every successful, creative, ingenious person on the planet, and it is this: success is inevitable. This is true because everything you do will lead to some kind of result. You will always succeed in getting an outcome. What matters is how you perceive the outcome, and also what you do with it.
Success is always a matter of perception. You can choose to see everything in life as an opportunity to learn. It really is as simple as that. Once you accept this, you give yourself permission to make mistakes, many mistakes, perhaps, if you need. However, these mistakes are no longer failures, they are learning experiences. Your mistakes offer you incredibly valuable information that you can use.
There is no such thing as failure, only feedback. When you accept this idea, you also accept the opportunity to make the changes necessary to produce your desired result. When you do not get your desired result, you can accept this as feedback and do something different.
If obstacles show up, rejoice. This means you are making progress. Know that you are always doing the best you can do with the resources you have, and you always have the opportunity to gain every resource you could ever need to generate the change you desire.
