is this retirement strategy enough, and how to allocate money over the next 25 years?

im planning a retirement strategy w/ a 25-year horizon, aiming to retire around age 60. im considering this monthly allocation:

-employer-funded retirement account: employer contributions for 25 years (automatically deducted from salary)

-global etfs: ₱30,000/month

-pagibig MP2: ₱6,000/month

-sss: ₱1,200/month

-remaining surplus: kept as liquid cash/savings

im deliberately keeping the etf contribution relatively low because i want to maintain liquidity rather than investing every available money.

the goal is to have enough retirement income/assets to live comfortably at 60.

wuld you structure this differently?

would you:

a. keep more money in cash for flexibility

b. increase global etf contributions to ₱50k–₱60k/month

c. keep the diversification between employer-funded account + etf + mp2 + sss

E) drop mp2/sss and focus mainly on employer-funded account + global ETFs

im particularly interested in opinions on whether maintaining a large liquid cash reserve is worth the opportunity cost of investing more aggressively.
