Try to improve. Don't expect too much, but don't feel discouraged either; keep up your enthusiasm; you will make progress.
Unlike physical progress, which is subject to natural restrictions, the qualities of the mind can be developed limitlessly.
In this century we have made remarkable material progress, but basically we are the same as we were thousands of years ago. Our spiritual needs are still very great.
For material progress and physical well being, peace of mind is of utmost importance.
The mind must be developed by you alone. There is no way for others to do the work and for you to reap the results. Reading someone else's blueprint of mental progress will not transfer its realizations to you. You have to develop them yourself.
