There are no means of finding what either one person or many can do, but by trying - and no means by which anyone else can discover for them what it is for their happiness to do or leave undone
Interpretation
True happiness can only be discovered through personal experience and effort.
John Stuart Mill emphasizes the importance of individual exploration in discovering what brings happiness. He argues that neither a single person nor a collective can dictate what will bring joy to another; it is through personal trials and attempts that one learns what actions lead to their own fulfillment and contentment.
In practice
During a motivational speech, the quote can be used to highlight the importance of trying new things for personal growth.
The peculiar evil of silencing the expression of an opinion is, that it is robbing the human race; posterity as well as the existing generation; those who dissent from the opinion, still more than those who hold it.

Political Economy, in truth, has never pretended to give advice to mankind with no lights but its own; though people who knew nothing but political economy (and therefore knew it ill) have taken upon themselves to advise, and could only do so by such lights as they had.
Marriage is the only actual bondage known to our law. There remain no legal slaves, except the mistress of every house.
Berlusconi is a genius in communication. Otherwise, he would never have become so rich.
In reality, there is, perhaps, no one of our natural passions so hard to subdue as pride. Disguise it, struggle with it, beat it down, stifle it, mortify it as much as one pleases, it is still alive, and will every now and then peep out and show itself; you will see it, perhaps, often in this history; for, even if I could conceive that I had completely overcome it, I should probably be proud of my humility.
We are men and our lot in life is to learn and to be hurled into inconceivable new worlds.
I used to work very long hours. Then I started to realize that the stuff that I was writing in the late afternoons, I was generally throwing out. So I quit earlier than I used to.
