Just as a bird soars through the skies on its two wings, so too does a mitzvah rise on the wings of love and awe. Moreover, loving God is a mitzvah, one of the six that apply at all times and in all places.
The problem is: how do we develop wings? In other words, if you don't love, what good is having a mitzvah, that is, an obligation to love?
The truth is, we were born with wings; we just need some exercise to keep them in shape and flapping. We have an innate love for God, but, as Maimonides writes, if we never think about God, it's difficult to feel love for Him.
And what can you think about? Here is a meditation, taught by Rabbi Shneur Zalman of Liadi:
In the morning, before prayer, contemplate the greatness of God. Ponder the wonders of His creation. Imagine what it takes to create such a place and keep it functioning and existing at every moment.
Then, observe your own smallness, how insignificant you are in the face of such greatness.
Now imagine how this incredibly great Creator is putting everything else aside (so to speak) to listen to your prayers, help you observe your mitzvot, study Torah with you, and generally help you live your life. His love for you is as infinite as He is.
Repeat it daily, until you get love.
Now you have wings, send some mitzvot flying! You have a purpose in this world, fulfill it out of love! It's much more pleasant than living grumbling.
That is why love is a contagious mitzvah: when others see someone whose life is motivated by love for God, they spread their wings to fly with them.
