Quote by Alfred Russel Wallace
"The greatest tragedy is not failure, but the refusal to even attempt the difficult."
More from Alfred Russel Wallace
"There is grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved."
"The beautiful world we live in is rich with infinite possibilities."
"The mind of man is capable of anything."
"Truth is stranger than fiction."
