Don't let yourself be weighed down by what other people think, because in a few years, in a few decades, or in a few centuries, that way of thinking will have changed. Live now what others will only live in the future.
If you go around promising what you do not yet have, you will lose the will to achieve it.
When we turn around & come face to face with our destiny, we discover that words (spoken) are not enough. I know so many people who are brilliant speakers but are quite incapable of practising what they preach. It's one thing to describe a situation & quite another to experience it. I realised a long time ago that a warrior in search of his dream must take his inspiration from what he actually does & not from what he imagines himself doing.
