In order to live an eternal life, you must develop a strong sense of realization that all things are temporary, but God is eternal. So, do the right things, and achieve all success you desire but don't attach yourself to them. In other words, Have a relationship with God and keep doing your part for this planet. You are sent here to do something big, so dare to find that purpose and fulfill that. However, don't disconnect yourself from God but keep detached yourself from all the earthly achievements. Keep reading more Bible Verses About Heaven and Eternal Life, and you will access more wisdom. "No man can obtain the gift of eternal life unless he is willing to sacrifice all earthly things in order to obtain it" (Gospel Doctrine, 5th ed. [1939], 261).
