Instead of seeing the rug being pulled from under us, we can learn to dance on a shifting carpet. First we form habits, then they form us. Conquer your bad habits, or they will eventually conquer you.
You must have long-range goals to keep you from being frustrated by short-range failures. An objective without a plan is a dream.
Argue for your limitations, and sure enough, they are yours. We can try to avoid making choices by doing nothing, but even that is a decision.
People are not remembered by how few times they fail but by how often they succeed. Every wrong step is another step forward. Until you try, you do not know what you cannot do. You are never given a wish without also being given the power to make it true. You may have to work for it, however. You cannot pick cherries with your back to the tree. You cannot cross the sea merely by standing and staring at the water. Do not let yourself indulge in vain wishes.
