You have to set down your mental baggage first before you can make a fresh start.
Tips
memory
包袱 is literally a cloth bundle carried on the back - the old traveler's pack. 'Put down the bundle' for any weight you've been carrying: grudges, guilt, pressure, past failures.
usage
Very common with 思想包袱 ('mental baggage') or 心理包袱 ('psychological burden'). Feels encouraging - the standard coach/therapist/manager phrase for 'stop overthinking and move on.'
