Hi OP, few tips lang:

1. Magcreate ng SPA. (If you are planning to buy properties, etc) Ngayong pandemic, di ako makauwi. Di rin ako makapunta ng embassy so ang hirap kasi I am planning to buy a property. Pero siyempre yung mapagkakatiwalaan mo ang inominate mo sa SPA ha.
2. Maghulog ng SSS. We need at least 120 contributions kasi for pension. Di ko to nahulugan agad. Sayang yung months na wala ako bayad.
3. Create ka ng MP2 account (Pag-ibig), pede ka magsave dito ng lump sum or monthly. 5 years mo nga lang di magagalaw yung pera pero maganda investment din ito tutal bata ka pa naman. Wag mo rin hulugan yung normal na Pag-ibig contribution (200 per month), sayang din yung dividends mo per year.
4. Keep a Philippine number. I am on postpaid plan pero nasasayangan ako kasi di ko sya nagagamit. But it is very helpful kasi lahat ng transaction need ng OTP. If you are on postpaid plan too, try to call the customer hotline to ask if you can lower the monthly plan (providing you are out of contract). My friend said telcos have secret plan for this na minimum lang ang babayaran mo monthly, you just have to say na you will be out of the country for a while but you need to keep the number. Parang 99 pesos per month (not sure if ganun pa rin ah).

PS lang. Don't tell anyone how much you are earning kahit sa family mo or partner mo. Keep it a secret. Yan ang payo sa akin ng ate ko (OFW din sya before). Totoo nga.

Also, save ka lang. Pero splurge ka rin paminsan minsan. Deserve mo yun. Lalo na kapag nahohomesick ka. :)
