If you sleep during seed time & planting, 

you will lack during harvest.  -God

If you had not been faithful during the  'I can't believe I have to do this' phase, you would never have made it to the ' I can't believe I get to do this' phase.  You are enjoying the momentum of 'want to' because you were faithful during the discipline of 'have to'. And what you sowed in faithfulness is being rewarded in fruitfulness.
