You can do so many different things with lemons.  I love to dry the slices and use them in crafts.  They make beautiful spring and summer wreaths.  I have covered them in translucent glitter and hung them on my holiday tree.  I've made fresh squeezed lemon aid for my lemon loving granddaughter.  I have made lemon dill butter sauce for my seafood.  I love seafood.  These are super easy to grow.  You just poke them down in the soil about a half an inch deep, water, and put them in a warm sunny window.  It won't be long before you have a great house plant with shiny dark green leaves.  Blooming and fruiting is going to take around 3 years.
