From there, deduct RM1k as emergency saving, then the rest are to spend on food

Not going to drive February at all because of planned vacation to Hanoi so yeah, based on this, I think driving Grab full time is reasonable if you don't have loan commitments, isn't looking to get rich quick, and value flexibility of time.

I did achieve the main goal of driving Grab instead of full time employment, which is spending more quality time with wife. There are still some concerns about doing this for the next couple years, but we'll decide after Grab announce the PSV thing, as in how they will go about it

Currently the decision is resume driving Grab full time in March after done with vacation
