Conditions: 只要…就 vs 只有…才
只要 A，就 B / 只有 A，才 B
只要 (zhǐyào) means the condition is ENOUGH: 只要你努力，就会进步 "as long as you work hard, you'll improve" — hard work alone gets you there. It pairs with 就.
只有 (zhǐyǒu) means the condition is REQUIRED: 只有多练习，才能说得好 "only by practicing a lot can you speak well" — no practice, no result. It pairs with 才. Swapping the partners (只要…才) is the classic slip.
