In this life, you can choose between two courses. You can either shut yourself up in a country house and stare into tanks, or you can be a dasher with the sex. You can't do both.
In the book "Right Ho, Jeeves" by P.G. Wodehouse, the author presents a humorous choice between two lifestyles. The idea is that one can either live a reclusive life, isolated and absorbed in solitary distractions, or choose to engage fully in social or romantic endeavors. These two paths are presented as mutually exclusive, suggesting a tension between introversion and extroversion.
The quote underlines the notion that life offers distinct choices that shape one's experiences and priorities. Wodehouse cleverly implies that indulging in both pursuits is not possible, thus inviting readers to reflect on their own life decisions and the importance of embracing one's true inclinations.
