Using the gifts that Hashem gives us.

Rabenu Yonah brings down that a person should do Teshuva at every meal.  He says that you should take that opportunity to reflect on what you have done since the previous meal.  If you did any aveiros you should do Teshuva and you should thank Hashem for all of the positive things that you did.

Rebbetzin Kalmonovitz explains that the reason that our meals are the appropriate time to do Teshuva is that at every meal we are receiving the gift of food from Hashem.  This food gives us energy.  If we use this energy to do good things then we are using this gift the way that Hashem means for us to use it.  If, chas v'sholom someone uses this gift, this energy,  to do something wrong, we are taking Hashem's gift and perverting it.

If we live our lives like this, always doing Teshuva at every meal, and reviewing our lives at every meal, we will live in a constant state of Teshuva.
