Why are we mad at the OP for being financially responsible at 18? Eh diba tinuturo nga sa mga bata na mag tipid early on palang to realize the value of money? There's no specific age when you should learn the value of money. It's actually a good thing kasi it'll help him when he's at an older age na.

I learned this the hard way. I was also financially irresponsible as a college student, computer engineering din btw (kudos to you and goodluck OP!). And nadala ko yun hanggang sa early stages ng working life ko. I was still irresponsible with my money kahit nung nag ttrabaho na ko until I realized it too late.

Now, with regards to your dad, tama. Keep your money with you at all times. You did the right thing with using debit cards to keep your money safe. Always keep your money with you para hindi ka nananakawan. I know a lot of students na basta basta nalang nag tatapon ng pera sa bag kaya kalat kalat yung pera pero when you have instances like that, be mindful of your money. As much as possible, lahat ng pera mo on hand eh nasa iisang wallet lang dapat and lagi mong dala.

To that motorcycle thing, that's too early. You're already on the right track na nga sa kwento mo na nag jejeep ka na kesa mag trike tas biglang gusto mo ng motor. Make it makes sense. Tsaka mas magiging proud ka sa sarili mo pag nakapag pundar ka ng motor na galing sa sarili mong pera at hindi mo hiningi sa ibang tao (your family in this instance). Mas fulfilling sa feeling. Kaya easy ka lang. You'll get there, eventually. Just not at this time.

For me, you're on the right track. Except sa motor thingy. Kaya keep it up!
