Anyone who makes an effort at whatever they hope to accomplish can, and will, seriously improve their chances of succeeding.
To accomplish great things, we must not only act, but also dream; not only plan, but also believe.
We make our own choices and we're each responsible for them. Blame and credit belong to the individual. You haven't the right to claim either from someone else.
Mistakes are a part of being human. Appreciate your mistakes for what they are: precious life lessons that can only be learned the hard way. Unless it's a fatal mistake, which, at least, others can learn from.
You can choose right now to change the way you are experiencing a windstorm. Adjust your sails.
