One thing life taught me: if you are interested, you never have to look for new interests. They come to you. When you are genuinely interested in one thing, it will always lead to something else.

The remark frames curiosity as a self-renewing habit rather than a finite resource. Roosevelt suggests that sustained, genuine attention to a subject generates its own momentum: one inquiry opens onto another, and engagement produces new questions, people, and opportunities. The emphasis is less on collecting hobbies than on cultivating an inward stance—interest as an active, receptive way of moving through the world. Implicitly, it also counters boredom and stagnation: the problem is not a lack of things to do, but a lack of invested attention. The quote thus reads as practical counsel for lifelong learning and resilience, grounded in the idea that meaning and novelty arise from committed involvement.
