YOU can be the one whom the Prophet (peace and blessings of Allāh be upon him)described as having all their previous sins wiped out!
“Whoever stands (in the voluntary night prayer of) Ramadan out of faith and in the hope of reward, his previous sins will be forgiven. And whoever spends the night of Lailat Al-Qadr in prayer out of faith and in the hope of reward, his previous sins will be forgiven.” [An Nasa’i]
What more motivation do we need Subhan Allah!? May Allah (glorified and exalted be He) make me and you one of these people, Ameen! A better question to ask ourselves is: what is holding us back? Stand in prayer for as long as you can. We have all stood for long periods of time preparing meals for guests, shopping for hours, or playing sports until our bodies ache. So why not do it this time for the sake of Allah (glorified and exalted be He)? Make your prayers longer, deeper and more meaningful. Remember: you may never, ever get this chance again.
