I have some spare time over the weekend mornings, are there any opportunities to earn additional income from home utilizing the weekend free time (maybe 3-4 hours each sat, and each sun). thanks!

Other than trying to budget, you should also increase your side income sources. One simple way is to sign up for milieu, use my referral code to get 500 more points when you complete 7 surveys . My code is 6RXyXgu. Download the app and sign up

Depends on what skills you have. grab?

Use the spare time to brainstorm extra income opportunities, e.g. how to value add at work for income increment, search for new job opportunities that give higher pay, read, learn and upskill, start a side business etc.
Otherwise, find hourly paid part time job at coffee shop/hawker/restaurant, or be grab driver if you own a car.

Can give tuition, like piano or smth that you have a skill in
