Pray as if Jannah is on your right side, Hellfire is on your left side, the siraat (bridge over Hellfire) is under you, the angel of death is behind you (waiting to take your soul any minute), your sins are above you (waiting to crush and destroy you), and this is the last deed, the one that decides if you go to Jannah or Jahannam forever.

Abu Ayyub Al-Ansari reported: A man came to the Prophet, peace and blessings be upon him, and he said, “O Messenger of Allah, teach me something, but make it concise.” The Prophet said, “When you stand for your prayer, then pray as if you are saying farewell. Do not say anything for which you must apologize, and abandon any desire to acquire what other people have.”
