To 'get to heaven' as you say is dependent on two things -- faith in the Manifestation of God in His Day, in other words in this Age in Bahá’u’lláh; and good deeds, in other words living to the best of our ability a noble life and doing unto others as we would be done by. But we must always remember that our existence and everything we have or ever will have is dependent upon the Mercy of God and His Bounty, and therefore He can accept into His heaven, which is really nearness to Him, even the lowliest if He pleases. We always have the hope of receiving His Mercy if we reach out for it.
