Temptation is one thing that is overrated, as well as underrated in life. Temptation simply means a desire to give in to your needs or wants even when it has adverse spiritual consequences.
You wake up in the morning, you're hungry. You cook food and eat. You've satisfied a need. There was no temptation involved. But if it was a day you decided to fast, and you wake up desiring that delicious pot of stew that you put in the freezer last night... Temptation has come calling.
Maybe you're not fasting. But your mum has given strict instructions not to touch that soup until she returns, and you're impatient, mentally hurrying her up to get home quickly. Temptation is knocking at your door.
When you're able to say "No" to it and do what you're supposed to do, then you've overcome it. But when you decide to answer to its call, you've fallen into temptation. Answering its call actually seems a smart thing to do at that moment it comes calling, but the regrets often set in soon after the deed is done. The consequences are usually more lasting, sometimes for the rest of your life.
