On a personal note, I am grateful to have had opportunities to journey into space. It took nearly ten years to see my dreams come true. It was indeed worth the effort and the wait.
In each of our lives, nobody knows what will be happen—nor be able to predict the circumstances or events of what may or may not occur in our futures. In any case, I make a conscious effort to never forget how very fortunate I truly am.
Before men and women, we are human beings. That is common sense. If you want to do something, go for it.
