This is just an encouragement when you feel you're active and there is little to confirm that anything you do is bearing fruit. Whatever you do in faith is seen by God, and He inspires you, whether you recognize it or not. As long as you remain in the comfort of His love, what you do, in work or play, is an expression of faith. So keep this in mind:
Eccl 11.6 Sow your seed in the morning,
and at evening let your hands not be idle,
for you do not know which will succeed,
whether this or that,
or whether both will do equally well.
