You don't seem to have enough confidence to start a new thing, to do what we like, to do something that changes everything for us. That's normal because the thing we wish to do is on everybody's wish list, but you are the only one to pursue it. You are the only one who have enough confidence to actually do it. Now how to gain that confidence?
We all have an instinct that if we do what we like to do, now or later we will be discovered and introduced to the world as what we are. But actually we are so terrified of the things between us and the goal. We tend to give more importance to the things that we are to lose and give in to the delusion that we not appreciating what we have at present.
But here is the idea, if we actually sure that we could achieve excellence in what we like, its time that we are glad about it and help ourselves to jump that hurdle of risk of losing things. The inevitability that we believe about doing what we love could help us do wonderful things, then why to cover that inevitability with short-sighted fear.
Great people would not have done what they've done if not for their courage in seeing this inevitability. And we all should have the same methodology if we are actually aiming on changing the world as it is now. People who are great are not the people who have better consequence, they are the people who believed that it is inevitable that they reach excellence when they do what they like to do.
Life turns out worth living only when you are doing what you like, only when you are what you are created to be. All the things that this world inflicts on us would leave us lifeless, unless we are in a place that we are proud of what we are doing. And else it would be a destruction.
Humanity doesn't need it to be just dragging the life forms on earth but it needs to be challenged, to be excellent, to be in a right path, to be rooted for the right principles and values, which is what humanity is defined as. Humanity needs humanity.
