Our own culture tells us that one who has care and interest will always succeed. (SSB 1974, p. 10)

Success comes to those who have Shraddha more than anything else. (JV, p. 58)

Whoever has enthusiasm, steadfastness, and the determination to reach the goal will certainly succeed. Cultivate that faith in ultimate success; never despair or cavil or doubt. This is My advice to one and all. Success is your birthright and you must get it, sooner rather than later. (SSS Vol.2, p. 151)
