Love comes in many forms, so is there a specific type of love you were hoping for? All magic of course only works if you understand the basics of magic, which includes energy work and visualizing. If you can do that, you can cast any spell. That said, if a spell should succeed or fail comes down to many factors, like if the spell was unneeded, the spell was written improperly, or the person you cast over was somehow blocking your energy from reaching them. All these things can effect a spells potential.
I would try a simple apple love spell. Hold an apple in your hands - wash and dry if you wish but do so mindfully - as you hold it, let the energy around you enter your body and pool in the apple, as you let the energy fill the apple visualize the love you wish to receive, reflect on how it makes you feel, fantasize about all the good that will come from it. When you feel ready, say "I open my heart to love, I open my heart to truth." Now eat the apple, still reflecting on the love you wish to welcome into your life.
