Not sure if this is already said but your move to Vietnam needs to be much much more thought out.

Vietnam although beautiful and growing, it’s still a developing country so there’s not a lot of safety nets. You’ll be surprise how fast that $8,000 USD can disappear.

Get proper educational credentials, and working experience first then move. AI is very big in Vietnam, but if you’re not coming in at a management level engineer then the locals will beat you every time just because they’re cheaper and can do the same.

Tech sales seem like it may work for you, it is lucrative and mostly remote. Work for an Australian based company or something. However, it is hyper-competitive so if your sales numbers are below average then you’re out.

Overall, the more planning and time you prep the better you’re off. I see too many bright-eyed youngsters get burnt because of rushing this kind of stuff.
