If the thing you wish to do is right, and you believe in it, go ahead and do it. Never mind about failure for every failure brings with a SEED of equivalent success.
Always remember, this world we live in is demanding new ideas, new ways to present ideas, new ways to communicate, new ways to teach, new leaders, new vehicles, new designs. The backbone of it all is the need for better, new and quality things. To win, you surely need definite purpose, knowledge and desire to create something new, better and more quality.
Put into practical use the new opportunities, new impulses and be a practical doer. Don’t be afraid of new ideas.
