Quote by Nikola Tesla

"The present is theirs; the future, for which I really worked, is mine."

"If you want to find the secrets of the universe, think in terms of energy, frequency and vibration."

"The day science begins to study non-physical phenomena, it will make more progress in one decade than in all the previous centuries of its existence."

"I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees his creation unfolding."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
