A 3-week overseas holiday requires a certain approach. We want all the essentials, but we want the baggage as light as possible. We want enough changes of clothes to accommodate weather and outings but no more.
The rest is stripped down to basics. We are on holiday, our routines change. Our requirements are limited to sight-seeing and exploring cultures, flavours and experiences.
Emigrating is a different ball-game. When we go for the long run we cannot only think of what we need for a 3 week period. We must consider what will become essential at some point during our tenure. Such occasions usually call for shipping containers of stuff.
Most of us went into lockdown prepared for a 3-week unplanned holiday and packed accordingly.
Welcome to your new home. Time to adjust your approach for the long haul. This is not the country you grew up in.
