There are many who have failed many times. They were losers. But they tried one more time. Then they succeeded. A winner is a loser who tried 1 more time.
When you try the next time, learn from your earlier failures. Alter the strategy, and execution if needed. But if you are sure about your idea, just try 1 more time. A winner is a loser who tried 1 more time.
Often, an idea fails because the time is not ripe. Just give it some time. But try 1 more time. A winner is a loser who tried 1 more time.
People take time to recognise your commitment in a new field. Your new idea cannot be an instant success. Give people time to adjust and recognise that you are good at your new calling. A winner is a loser who tried 1 more time.
