The most important lesson learned after striving to save money at age 30 is understanding balance and not shortchanging oneself! Loving oneself allows for better care of those who matter most.
How many people understand how to make this balance, some have been privileged with several opportunities in which they misused them, some were left with indecision on matters like this, while some lack the way of effectively managing themselves for a better future, all they will think is that things will continue the way it was without knowing that change is made constant for everything in life, at age 30 i don't expect someone to still be struggling on how to make savings in life.
Trying to make yourself happy and not stressed is hard, if you are having financial issues. Right now, I am in by far the worst time in my entire life regards to finance, hopefully it will get better very soon but for a few more months I am going to end up with a terrible result, so it is not going to be that easy at all. At that point, you can't just "take care of yourself", you just can't at all. While we are talking about something like this, all I want to remind people that if you are not having anything life threatening sickness levels, then you should find a way to be happy.
Debt, relationship troubles, and many other things in life that are temporary and not regards to death, are small things when you consider the permanent state of death. So, just find a way to be better and try to make sure that you balance your life and also your finances at the same time. This will make it better for you and it would make it better for everyone else too.
