The first requirement is courage. Fear of failure, judgment, criticism, and the unknown freezes most people before they ever take the first step. There are more reasons and for everyone there are more heavy and pressing ones.
Starting demands accepting that you will look foolish, that you may fail publicly, and that the outcome is not guaranteed. Courage here is not the absence of fear but the willingness to move forward anyway. Every significant achievement in history began with someone deciding the discomfort of beginning was preferable to the regret of never trying.
You don’t need my permission or anyone’s, for in the end you will know you did nothing. The failure to courageously act generally lead to hate, resentment, and regret.
Take one courageous small step this week. It can be as simple as writing down what you want, then researching it. Welcome the mistakes and errors in judgment.
