Avoid using short-term rewards as a motivational tool.
Intrinsic motivation, i.e., motivation from within, typically produces much more effective results than external motivation, such as a short-term reward system.
Using short-term rewards to motivate others, or yourself, to complete a task is rarely the most effective motivational tool you can use. However, there are exceptions to this rule. Generally speaking, it’s best to use short-term rewards as a last resort for tasks that cannot be completed without any other external motivational tools.
