On the authority of Abdullah ibn Umar (May Allah be pleased with them both), he relates that the Prophet (Peace be upon him) once held my shoulders and said:
“Live in this world as (if you are) a wayfarer or a stranger.” And Abdullah ibn Umar (May Allah be pleased with them both) used to say: “If you live till night, then do not wait for the next day (i.e. do not have hopes that you will live to the next day), and if you wake up in the morning do not have hope that you will live till the night. And take (advantage) from your health before your sickness and take advantage of your life before your death (i.e. do every possible obedience in your life before death comes to you for then no deeds can be performed.)”
[Bukhari and Tirmidhi]
And a traveler carries with him only the the really basic needs. Get rid of jealousy, envy, hatred, disobediance, bad memories, bad habits, sins, and travel light.
Also, Rasulullah (S) advised, "Fear Allah wherever you are, and follow up a bad deed with a good one and it will wipe it out, and behave well towards people." From the 40 nawawi ahadith.
so all these bad deeds that are worrying you can be replaced by good.
Rasul Allah (sal Allahu alaihi wa sallam) said: "Save yourselves from the fire of Hell even if it be by giving away a bit of a date, or by uttering a good word." [Sahih Bukhari]
Rasul Allah (sal Allahu alaihi wa sallam) encouraged us to do good deeds, even if they appeared to be very small. He (sal Allahu alaihi wa sallam) said: "Do not look upon any good work as insignificant, even if it be emptying a bucket into the vessel of one asking for water, or receiving a brother of yours with a pleasant face." In an advice to women he said: "O Muslim women, no woman should look upon sending a gift to her neighbor as mean, even if it be the hoof of a goat." [Sahih Bukhari]
