This quote emphasizes the importance of determination and decisiveness once a decision has been made. It suggests that once a person has made up their mind about something, they should remain steadfast in their decision and not let second thoughts or doubts (‘if’ or ‘but’) deter them from their chosen path. This is a call to commitment, to the power of a made-up mind, and to the resilience required to stick to one’s decisions, even when faced with challenges or obstacles.

The quote also underscores the notion of eliminating ambiguity and uncertainty in one’s decisions. The words ‘if’ and ‘but’ often introduce conditions or doubts, and by stating there is no longer any ‘if’ or ‘but’, the quote encourages us to be clear, unambiguous, and resolute in our decisions.

Applying this idea in today’s world or in personal development could mean that once we’ve made a decision—whether it’s about our career, relationships, or personal goals—we should stick to it and not allow doubts or potential obstacles to sway us. It means that we should commit fully to our decision and do everything we can to make it work, rather than second-guessing ourselves or contemplating alternatives.

In personal development, this could translate to setting a goal and sticking to it, regardless of the difficulties that may arise. For instance, if one decides to pursue a healthier lifestyle, they should commit to that decision by consistently exercising and eating healthily, without allowing excuses or temporary setbacks to derail their progress.

In a broader societal context, this principle could be applied to any decision-making process, from business strategies to policy-making. Once a course of action has been decided upon, it should be pursued with determination and commitment, without allowing doubts or potential challenges to weaken the resolve.

However, it’s also important to note that while this quote encourages steadfastness and resolve, it should not discourage flexibility and adaptability. Sticking to a decision doesn’t mean ignoring new information or refusing to adjust one’s course when necessary. It’s about maintaining one’s commitment and focus, but also being willing to adapt and evolve as circumstances change.
