Parents, able to share how you save money? No savings investment plans. i been trying but i just don't seem to get it down. Despite writing or locking it aside

At the moment my savings goes into OCBC Bonus plus account. while my pay is from DBS. So each month once I get my pay, I have an auto-transfer of 300 into the OCBC account. The good thing about this account is you get bonus interest rate if you DO NOT withdraw. So just to earn this extra bonus, I always tell myself that the money go in cannot come out. So far I only withdraw from that account once, which was to pay for the hospital bill. I don't even know how much is inside and I tell myself I don't want to see the balance until I get my house 4 years from now.
