The quotation presents persistence as a central condition of achievement. Its emphasis falls on remaining committed to an aim for long enough to make progress, particularly when results are not immediate. The phrase “stick to it” suggests sustained effort rather than a single act of determination, linking success with patience and continued engagement.

Taken literally, the claim that people can do “anything” is an overstatement, since ability, circumstances and external limits can affect what is possible. Its practical meaning is therefore better understood as an encouragement not to abandon realistic goals too quickly. The quotation reflects a broader idea about character: worthwhile achievements often require repeated effort over time, and temporary difficulty does not necessarily mean that a goal is unattainable. It can be applied to learning, creative work and other long-term undertakings where progress depends on persistence.
