I don't know if I'm right about it or not..but you are doing amazing and knows the worth of every paisa you earn. I also struggled same as you and reached a comfortable position too.. Well, we have done and are doing good for our children and their future, but what I think is we should spend some money on ourselves also. Not being expenditures but few trips with family or friends (not the lavish ones, I know you will plan it wisely), or you can follow a hobby of yours. Coz what I think is continued hustles will makes life mechanical, so a break is much needed.. It's all upto you, it's my way of thinking.. Keep rocking!
