Lost at 20?

Hey guys,

Im abit lost at the moment. Some details: Im 20(born 2003), married with 1 3 month old. Lifes pretty cruisy I wont lie, Expenses are paid with nearly double available for savings. However I notice my expenses are low as of current. I cant help but feel like I dont know what im doing with life?

Currently on $55k p.a, KS at 4% but only a 3% match, taking home about $1600/fortnightly post tax. Although I do earn commission of around $2k post tax each month. My partner also brings in roughly $1400/fortnight post tax.

Expenses fortnightly: Rent:$770 Debt:$160 (debt total is $10k) Groceries:$250-$300 Gym membership+ coach(I powerlift):$150 Utilities:$70 Fuel:$120 Data:$40

Total: $1610 on the higher end. Income:$3000($4000 after commission)

However I seem to compulsively spend almost everything all the time. I want to save for a house, however I feel like im hopeless at saving anything. Any tips?
