Never undervalue yourself. Believe in yourself. Believe that you can do your work well, and then make good. Never doubt yourself. Faith in one’s self unlocks those hidden powers that all of us have, but that so few of us use. Every man and woman has undeveloped strength undreamed of until emergencies call it forth. Every one of us has been surprised at how much we can do and how well we can do it when we have to do it.
Do not wait for these emergencies to call out the might within you. Realize your assets every day. God has made an investment in every one of us; shall we go to Him when our life is done giving Him no return upon that investment? When He invested in you He meant that you should pay Him dividends in the betterment of the world and helpfulness to your fellow-men. You can do this only by your best work. And your best work is possible only by faith in yourself and by love of your work.
