Shakespeare's Sonnets: So are you to my thoughts as food to life

So are you to my thoughts as food to lifeOr as sweet season'd show'rs are to the ground;And for the peace of you I hold such strifeAs 'twixt a miser and his wealth is found,Now proud as an enjoyer, and anonDoubting the filching age will steal his treasure,Now counting best to be with you alone,Then better'd that the world may see my pleasure,Some-time all full with feasting on your sight,And by and by clean starvèd for a look,Possessing or pursuing no delightSave what is had, or must from you be took. Thus do I pine and surfeit day by day, Or gluttoning on all, or all away.
