This quote is suggesting that if one wants to be successful, they should pay attention to the advice given by those who are older and more experienced. The speaker asserts their wisdom is a result of their age and the experiences they’ve had over time. The phrase "mark what I advise" implies that the speaker’s words should not just be heard, but taken seriously, considered carefully, and acted upon.
In terms of personal development, this quote is emphasizing the importance of mentorship and learning from those who have walked the path before us. It is about being humble and open-minded enough to accept that we do not know everything and that there is value in the wisdom of those who have more life experience.
In today’s world, this could be applied in various contexts. In a professional setting, it could mean seeking guidance from senior colleagues or industry veterans to navigate career paths or overcome work challenges. In academia, it could mean learning from the insights and research of established scholars. In a personal context, it could mean listening to the life lessons shared by our elders.
However, it’s also important to note that while we should respect and consider the advice of those older and more experienced, it doesn’t mean we should blindly follow it. Everyone’s experiences are unique and what worked for one person might not work for another. Therefore, while it’s wise to learn from others’ experiences, it’s equally important to use our judgment to decide what advice to apply in our own lives.
