Between saying you are going to do something, there is a huge gap. Some of us never get to fill that gap, let it be fear or laziness. It is true that one may be better at something than the other, however the one that actually does it becomes immediately better. Why? Because he or she actually did what they said they were going to do.
I have always wanted to do many things, and because of fear of getting my work, or myself, rejected I don´t do it, not even the great ides that I come up with. I have criticized the work of many and claimed to be better just because I see their mistakes. But, herewith, I accept I am not better until I do it and I congratulate those that actually do what they say, those that complete their ideas. It is really a hard thing to do.
