Rebbetzin Heller says that this is one of the most important things we will ever learn.

There are 2 things that a person should always daven for:
1) Hashem should strengthen our heart to be devoted to Hashem singularly and not forgot the reason we are in the world. and that the burdens of life not distract us from the reason that we are in the world.
2) Hashem should strengthen our bodies and limbs to be able to do the mitzvot. That our bodies should be able to be strong enough to do what we need to do, because this world is a world of deed, and you can't do the deeds without energy.
Everyone has the same Mitzvot but we do not all have the same path to the mitzvot.

From the Shiur on Naaleh :
Depend Solely on G-d
