Spiritual literature can be a great aid to

Spiritual literature can be a great aid to an aspirant, or it can be a terrible hindrance. If it is used to inspire practice, motivate compassion, ad nourish devotion, it serves a very valuable purpose. If scriptural study is used for mere intellectual understanding, for pride of accomplishment, or as a substitute for actual practice, then one is taking in too much mental food, which is sure to result in intellectual indigestion.

Always believe in yourself and always stretch yourself

Always believe in yourself and always stretch yourself beyond your limits. Your life is worth a lot more than you think because you are capable of accomplishing more than you know. You have more potential than you think, but you will never know your full potential unless you keep challenging yourself and pushing beyond your own self imposed limits.
