A school life isn't an impediment for becoming full time devotee, it is the question of devoting oneself sincerely to Krishna Consciousness. To prosecute Krishna Consciousness there is no limitation, no material impediment can stop progress of Krishna Consciousness. That is the symptom of spiritual life. Spiritual life doesn't depend on material conditions.

  The darkness has no existence in the presence of sunlight, similarly Maya cannot exist in the presence of Krishna. As darkness and light exist eternally, similarly, Maya and Krishna exist eternally, but Maya has no existence in the presence of Krishna. Try to understand this simile.

Krishna Consciousness is difficult job for less intelligent persons. But one who understands Krishna Consciousness and acts accordingly, he should be accepted as spiritually the strongest man. In the Chaitanya Charitamrita it is said that persons who take to Krishna Consciousness are supposed to be the most intelligent men.

In the material world, the gold box and the gold plated box may be different in price, but in the spiritual world there is no such distinction. There the gold box and the gold plated box are the same. In material world there is difference between a sweeper and a cook; in the spiritual world a person who sweeps the temple and a person who worships in the temple are all the same. That is absolute knowledge.

A devotee always accepts his distress as minimized by God's Mercy, although he would have to suffer many more times the suffering.  Any one who accepts this philosophy of God's Mercy in suffering conditions, and still makes progress in Krishna Consciousness, it is said that he is sure to go back to Home, Back to Godhead.
